Abstract:

AbstractMarine site investigations are reviewed briefly, in terms of suitable drilling platforms and craft for various conditions, requirements for permissions and service locations, marine ground investigation methods and marine survey methods including geophysical profiling.The wide range of marine site investigation methods is illustrated and the appreciable differences from land site investigation methods are noted. It is suggested that BS 5930 does not give sufficient guidance on marine site investigations and that this situation should be rectified.

Abstract:

AbstractIt is water that makes the difference between a dried-out clay as hard as a brick, and mud. The dry fields of summer can become a quagmire for construction work.Examples are given of rapid deterioration of chalk when allowance had not been made for the effect of a known high water table when excavation went below it and the effect of water on loose backfill at an opencast site. Houses had been built before the water level rose in the old pit and were damaged by the resulting settlements.Soil fabric can make the overall field permeability much greater than that obtained from tests on small samples and completely upset predictions of quantities of water and number of wells required for ground water lowering.Out of balance water pressures caused by allowing the water level in a borehole to be much below the ground water level can lead to low SPT N values and disturbed samples. The result could be unnecessary expense on the new works.False results may be obtained if excessive pressures are used in making field permeability tests such as the Lugeon test. On the other hand, hydraulic fracture tests can be used to obtain an assessment of total stress conditions in the ground.

Abstract:

Abstract Geotechnical investigation is a cyclic process. The interdependency between different steps involved in whole process, i.e., from planning, performing investigation, transporting samples and analysis of data obtained from field or lab, present opportunities for improvements and further discussion. For estimating number of investigation sampling points required for a particular site and selection of investigation methods, today we mostly relay on information from previously conducted site investigations, local experience from that area or site. In geotechnical investigation getting field samples which represents actual ground conditions for the whole site is well known challenge and has been highlighted in many research papers. In this paper we are presenting concept of influence region of geotechnical investigation points and an approach for estimation of the same. We believe the influence region concept; its estimation approach will provide a mathematical model and will help in deciding number of sampling points at the geotechnical investigation sites. In author’s opinion the presented concept will further improve the quality of geotechnical ground investigation process and will provide help in getting representative, quality field samples for laboratory analysis. The presented concept and estimation approach in this paper is based on author’s field experience and exposure gained from working in Swedish infrastructure projects. We think the influence region concept will further improve the existing geotechnical ground investigation process and will open opportunities for its validation through focused scientific research. A brief overview of the existing ground investigation processes has been covered in the paper, along with examples from geotechnical site investigations from Trafikverket (The Swedish Transport Administration) projects in Sweden.

AbstractA review of the recent past leads one to conclude that the UK has an over capacity in terms of consultancy, specialist contracting and professional staff. This will have to be brought into balance.Factors likely to affect the future are discussed—technological breakthrough, legislation, certification, litigation, and market attitude.The fragmented organisation of the five basic activities of SI are considered and it is suggested that there is much to recommend the appointment of an independent geotechnical consultant, who would accept total responsibility for the SI.

AbstractGuidance on planning and design of site investigations is not explicitly included in the Code of Practice for Site Investigations (1981). Insufficient emphasis is given to developing a strategy and a programme of activities which is relevant to the proposed development and ground conditions.A more formal approach to the organisation of these preliminary stages is presented and an outline given for a planned programme of administration.Guidelines are given on how to develop an appropriate strategy including categorisation of investigation, preliminary design assessment and detailing site work. The need for records and refinement is highlighted.

Abstract:

Site investigation works is very essential in every construction design work. Soil type and shear strength are the important parameter to design foundation system of insfrastructure project. Site investigations are not only costly, but also time consuming. There many geotechnical engineers tend to reduce site investigation works to decrease the construction cost. Based on these problems, the study was developed on site investigation database for Pulau Indah, Klang, Malaysia using Geographical Information System (GIS). Research study applied the Thiessen polygon method to obtain existing some informations type of soil and shear strength on this site. The research result was the database and map information. These data can be used for civil engineers to obtain site informations of soil type and shear strength parameter for future construction work related to the area.

Abstract:

A detailed offshore site investigation was conducted in the Hibernia field in 1983 to provide engineering data for the preliminary design of a gravity base structure (GBS) for use as an oil production platform. Reliable information regarding the strength and variability of near-surface soils was needed to verify that the foundation would be capable of resisting large environmental design loads, including those induced by iceberg impacts and storm waves. This paper presents an overview of the geotechnical equipment and methods that were successfully used to complete the investigation, major results of the field and laboratory program, and an interpretation of soil strength parameters needed for analysis of GBS stability under the design loads. Results are presented that confirm that the preshear density and effective confining pressure, or "state," of underlying sand elements are major factors that must be considered when establishing design parameters for GBS structures. It is demonstrated that consideration of state changes resulting from GBS installation is important in the analysis of granular soil resistance under both drained and undrained loading conditions. Failure to account for this effect could lead to an unconservative design. Key words: Hibernia, offshore site investigation, CPT, sand strength, state parameter.

Abstract:

Abstract. In recent years, unmanned aerial vehicles (UAVs) have become widely used in emergency investigations of major natural hazards over large areas; however, UAVs are less commonly employed to investigate single geo-hazards. Based on a number of successful investigations in the Three Gorges Reservoir area, China, a complete UAV-based method for performing emergency investigations of single geo-hazards is described. First, a customized UAV system that consists of a multi-rotor UAV subsystem, an aerial photography subsystem, a ground control subsystem and a ground surveillance subsystem is described in detail. The implementation process, which includes four steps, i.e., indoor preparation, site investigation, on-site fast processing and application, and indoor comprehensive processing and application, is then elaborated, and two investigation schemes, automatic and manual, that are used in the site investigation step are put forward. Moreover, some key techniques and methods – e.g., the layout and measurement of ground control points (GCPs), route planning, flight control and image collection, and the Structure from Motion (SfM) photogrammetry processing – are explained. Finally, three applications are given. Experience has shown that using UAVs for emergency investigation of single geo-hazards greatly reduces the time, intensity and risks associated with on-site work and provides valuable, high-accuracy, high-resolution information that supports emergency responses.

Abstract:

Site investigations provide characterization of soil properties, but inevitable uncertainty remains at locations that have not been examined. Only a limited scope of site investigation can be conducted due to budget and time constraints, hence there are always risks associated with design based on limited investigation information. An efficient geotechnical site investigation should involve choosing the optimal number and location of borehole sites to gain adequate information for a given cost. Using a slope as an example, this paper proposes a framework to find the best sampling location that gives the most information while minimizing the probability of making the wrong decisions. The results suggest that the slope crest appears to be the optimal location to conduct geotechnical site exploration for slope stability assessment.

Abstract:

Insufficient or inappropriate soil testing can lead to a range of undesirable consequences, and yet there is no guideline for optimal investigation. This study analyses the influence of test type, number of boreholes, data interpretation, soil conditions, and structural configuration on site investigation performance. In addition to providing general recommendations, the relative sensitivity of these variables on performance is determined. Performance is assessed in terms of total expected project cost while implicitly incorporating the risk of damage from poor investigation. The framework for this study involves the use of randomly generated, variable, single layer virtual soils in a Monte Carlo analysis. It was found that optimal investigations can produce net savings in the order of several hundreds of thousands of Australian dollars, and key features of a future site investigation guideline are identified.

Abstract:

The Heifangtai plateau, having an area of about 14 km2, has experienced more than 70 loess landslides since 1960s. Aiming at investigating the slope instability induced by irrigation, a field test was proposed. As an important part of the field test, a detailed site investigation was conducted systematically. The topographical details of a typical loess slope at Heifangtai were obtained by a 3D laser scanner. The cracks and the plan view of the site were obtained using GPS. The lithological profile, groundwater level, sampling and soil permeability, were also investigated respectively. On the basis of the site investigation, the field test was conducted successfully.

Abstract:

The Williamson Site (44DW1) was recently re-examined after a seventeen-year cessation of its investigation. Williamson is a well known, highly investigated, quarry-related Paleoindian/Early Archaic site located in Dinwiddie County, Virginia. Situated at the northern end of the site is a hillside and creek where primary and secondary sources of cryptocrystalline material are thought to exist. Past investigations have demonstrated that the hillside contains undisturbed artifact deposits dating to the Paleoindian Period (ca. 9,200–8,000 B.C.). The hillside is also where recent excavations were completed. This article presents some of the results of this recent examination.

Abstract:

Aims and methodA cross-sectional survey was performed on 318 patients receiving depot medication. The presence or absence of a depot site reaction was recorded by psychiatric nursing staff on a standardised form.ResultsSeventeen per cent of patients were found to have clinically significant depot site reactions. Such reactions were associated with increased frequency of injection and increased total volume of depot administered in the previous 12 months. The severity of a depot site reaction was unrelated to the concentration of depot preparation administered.Clinical implicationsDepot site reactions may be reduced by maximising the interval between injections and using low volume (highly concentrated) preparations of depot neuroleptic medication.

Abstract:

AbstractCurrent site investigation is predominantly based on routine sampling in exploratory boreholes, with transport and testing of samples at a distant laboratory. A number of specialised in situ techniques and tests have grown around the initial premise of using boreholes.The paper describes the development of parallel alternative techniques using test pits for trials and tests which the writers' have used in practice. The British Standard, BS 5930, briefly describes test pits but in general is related to current practice using boreholes. It is hoped that the paper will supplement the present Standard in this area.The in situ test techniques described are for dynamic and static penetration tests. The miniaturised trials model foundation pressure, compressibility, permeability and compaction.Relatively new techniques for pit plate bearing tests and penetrometers mounted on an excavator bucket, which utilise the excavator as a site robot, are presented.

Abstract:

This paper presents an overview of the soil profile characteristics at strong motion station (SMS) locations in the Christchurch Central Business District (CBD) based on recently completed geotechnical site investigations. Given the variability of Christchurch soils, detailed investigations were needed in close vicinity to each SMS. In this regard, CPT, SPT and borehole data, and shear wave velocity (Vs) profiles from surface wave dispersion data in close vicinity to the SMSs have been used to develop detailed representative soil profiles at each site and to determine site classes according to the New Zealand standard NZS1170.5. A disparity between the NZS1170.5 site classes based on Vs and SPT N60 investigation techniques is highlighted, and additional studies are needed to harmonize site classification based on these techniques. The short period mode of vibration of soft deposits above gravels, which are found throughout Christchurch, are compared to the long period mode of vibration of the entire soil profile to bedrock. These two distinct modes of vibration require further investigation to determine their impact on the site response. According to current American and European approaches to seismic site classification, all SMSs were classified as problematic soil sites due to the presence of liquefiable strata, soils which are not directly accounted for by the NZS1170.5 approach.

Abstract:

When investigating a fire type event, one has to have in mind that maybe the most important aspect is the identification of the source of ignition. Nowadays, commercial and open-source software are available and can be used during such investigations. The fire field model - Fire Dynamics Simulator (FDS) is one of the most popular numerical model used for fire investigation. The purpose of this paper is to demonstrate the importance of computer simulations when two hypotheses, Arson effect with multiple fireplaces and electric short circuit are taken into consideration as the cause of the fire. To virtually simulate the findings at the fire site, the FDS tool (Computational Fluid Dynamics) was used. Computational simulations for the two scenarios revealed that the multiple fireplaces scenario, the initial ignition at both the warehouse and the roof of the annex, illustrates the effects of the fire in a similar way to those found at the site, while the scenario with the initial source on the wall of the room with the electrical panel produces a fire located at the level of the construction and is not transmitted to the annex. Consequently, the results obtained validate the multiple outbreak (Arson effect) scenario.

Abstract:

The soil investigation performed on site identifies the physical and mechanical properties of the soil under the present road structure as well as the nature and thickness of the road structure to rehabilitate it when the road surface condition becomes poor or defective due to ageing, weathering and road traffic action. The rehabilitation processes re-assess the soil parameters to restore the pavement surface to the required level of service based on the recommendations of the field stratification as well as of the geotechnical characteristics of the studied emplacement. The paper presents the soil investigations on site along DN29 Suceava-Botoşani-Săveni-Manoleasa, Km 18+075 section of national road in Romania to get the information on subsurface conditions. The national road DN29 Suceava-Botoşani-Săveni-Manoleasa is covering the north-eastern part of Romania, in Moldavia region. Since its asphalt works in the '70s and '80s, nothing but partial sections of asphalt works has been carried out having never undergone major repairs. Due to external factors such as rain, snow, and traffic, the minor works that had been made make it usable for a short time, the results of soil investigation clearly attesting the rehabilitation priority. Some geotechnical characteristics of the national road DN29 Suceava-Botoşani-Săveni-Manoleasa, Km 18+075 section in Romania appear in comparison with those identified on site on the road DN29A Suceava-Dorohoi-Darabani, Km 50+075, in Romania, under a road structure that needed rehabilitation works as well.

Abstract:

Geotechnical design is based on site investigations which provide a reasonable overview of the soil profile and a realistic estimate of the geotechnical properties of each component layer. Nevertheless, when centrifuge modelling is involved, in situ tests become an additional challenge mainly because of limitations of in-flight procedures, but also due to the miniaturization of regular tools. As centrifuge modelling is becoming widespread, mostly as a result of decreasing electronic and computer costs, miniature site investigation tools are being designed to provide proper geotechnical information about model layers. This paper examines the development of site investigation tools to assess the strength of models during centrifuge tests. These tools are a T-bar penetrometer and a Cone Penetration Test (CPT) apparatus capable of measuring the resistance of clay and granular soils, respectively. These tools were used in a number of centrifuge tests on clay soils and silty tailings respectively. Both tools were tested and the results compared with centrifuge tests, in situ conventional tests, triaxial and direct shear laboratory tests showing an overall consistency and reliability of the measured data.

Abstract:

An experimental investigation to explore the interaction between bubbles forming at adjacent nucleation sites is presented. The results obtained are consistent with the results of Calka’s and Knowles’ experimental investigations and confirm that nucleation site activation/deactivation, whereby a bubble growing at a nucleation site is able to promote/hinder the formation of a bubble at an adjacent nucleation site by depositing/displacing a vapor nucleus in the nucleation cavity, is instrumental in determining how a bubble forming at a nucleation site influences the nucleation of the subsequent bubble at an adjacent nucleation site.

Abstract:

This paper reports the results of excavations conducted at the Mort Creek Site Complex, located in the Rodds Peninsula Section of Eurimbula National Park on the southern Curtis Coast, Central Queensland. Cultural and natural marine shell deposits were excavated and analysed as part of an investigation of natural and cultural site formation processes in the area. Analyses (including foraminifera studies) demonstrate a complex site formation history, with interfingering of cultural and natural shell deposits (cheniers) in some areas of the site. Radiocarbon dating indicates that Aboriginal occupation of the site was initiated before 2,000 cal BP, overlapping with dates obtained for natural chenier deposits.
