Abstract:

Dynamic Cone Penetration Tests for LiquefactionEvaluation of Gravelly SoilsMichael H. TalbotDepartment of Civil and Environmental Engineering, BYUDoctor of PhilosophyIn North American practice, the Becker Penetration Test (BPT) has become the primary field test used to measure penetration resistance of gravelly soils. However, this test is expensive and uncertainties exist regarding correlations and corrections for rod friction. As an alternative, the dynamic penetration test (DPT) developed in China has recently been correlated with liquefaction resistance in gravelly soils. The DPT equipment

Abstract:

Cone penetration test (CPT) is a fast and reliable site investigation tool for exploring soils and soft ground. While the interpretation of the test results in clay has advanced considerably from a theoretical and numerical viewpoint that of tests in sands still relies largely on empirical correlations. A major source of such correlations comes from tests done in calibration chambers (CC), where soil state and properties might be tightly controlled. Calibration chambers are relatively large pieces of equipment, and calibration chamber testing is expensive and time consuming. Moreover, CC tests

Abstract:

The quasi-static penetration of a cone penetrometer into clay can be formulated as a steady state problem by considering a steady flow of soil past a stationary cone. The soil velocities are estimated from the flow field of an inviscid fluid, and the incompressibility condition is achieved by adopting a stream function formulation. Emphasis is placed on obtaining an accurate velocity estimate and this is accomplished by a solution of the Navier-Stokes equations. The strain rates are evaluated from the flow field using a finite difference scheme. The clay is modelled as a homogeneous incompress

Abstract:

The Cone Penetration Test (CPT) was developed originally in Holland in the 1930’s as a device which provides a small scale model of a pile foundation. Early versions were simple cone points for which the only measurement was the thrust required to push the point through the ground. Over the past 20 years, the cone was standardized to a tip area of 10 cm², and an electrical version was produced, which allows for continuous measurement of the cone tip resistance and sleeve friction along with a computer-based data acquisition system. The electrical cone represents a significant step forward for

The results of field vane and cone penetration tests from five lower mainland sites are presented in relation to the different proposed correlation techniques.

However, as case history information has come to light, it has become apparent that silty sands are commonly involved, and in some cases even silts.

Abstract:

Due to lack of soil sampling during a conventional cone penetration testing (CPT), it is necessary to classify soils based on recorded tip and sleeve friction and pore pressure (if available) values.

Moreover, size and quality of databases used in the development of these soil classification models are undocumented and thus questionable. Similar limitations do also exist in the develop

Failure of tailings dams can occur due to liquefaction of saturated and loosely deposited silt and sand sized tailings under both seismic and static conditions.

As tailings possess soil-like structure and grain size distribution, it is possible to use ground improvement measures typically used for soils to improve the stability of these dams. It is also possible to use densification techniques to reduce the volume of the in-place tailings to provide greater storage space. This thesis reviews the assessment of ground densifica

Abstract:

One of the most critical problems geotechnical engineers face with is the determination of the amount of consolidation settlement that will occur at a site as a result of the construction of a structure. The compressibility behavior of the soil is an important parameter in determining the amount of consolidation settlement. The goal of this study is to develop probabilistically based correlation between the compressibility behavior of soil and in-situ test data. Within the scope of this research effort, performed CPT tests and the recorded settlement case histories where consolidation settleme

Abstract:

The master‘s thesis focuses on testing the shotcrete prepared in laboratory conditions. The main observed properties are compresive strenght of shotcrete and modulus of elasticity. The aim is assessment of methods for measuring those parameters. The calibrating correlations for strenght characteristics of shotcrete are given by obtaining the results of used methods. The shotcrete composition, amount and type of accelerating additive as well as economic aspect of using shotcrete is also assessed.

Abstract:

When bonded joints are subjected to harsh environmental conditions, the interphase, the three-dimensional region surrounding the adhesive/substrate interface, becomes critically important. Frequently, failure occurs in this region after adhesively bonded systems are subjected to elevated temperature oxidative aging. In a previous study, this was found to be the case with a polyimide adhesive bonded to chromic acid anodized (CAA) Ti-6Al-4V. The objective of the current research has been twofold: 1) to investigate the effect of thermal aging on the interphase region of polyimide/titanium adhe

Abstract:

L’identification des sols liquéfiables et le comportement de sols face aux sollicitations cycliques représentent des défis important en géotechnique. Différents essais, en laboratoire ou in-situ,sont utilisés pour évaluer ce phénomène. Le groupe Equaterre, en particulier, développe un pénétromètre statique à pointe cyclique qui permet d’imposer une variation cyclique de la force sur la pointe, par le biais de tiges centrales coulissantes, et de mesurer les déformations qui en résultent. Ceci permet d’accéder directement à la réponse du sol en place, et potentiellement de mettre en évidence une

Abstract:

This work is aimed at the reconstruction of the upper Quaternary depositional architecture, below the urban area of Ferrara, in northern Italy. The study area is part of the lower alluvial plain of the Po and Reno rivers and is therefore dominate by fluvial channel sands, levee sands-silts, and interchannel depression mud. The research was focused on the reconstruction of a digital geological model of the sedimentary bodies buried in the first 35 m under the topographic surface. The study units accumulated through Holocene and late Pleistocene times. The research work is based on the ana

Abstract:

Dredging activities at Ports and Harbors are inevitable for the safe navigation of ships and vessels. Dredged material may range from very fine and contaminated sediments to sand and gravels. While, granular dredged material can be directly utilized in civil engineering applications, fine sediments may require further treatment before use. In geotechnical context, fine sediments are characterized by low shear strength and high compressibility. However, these unfavorable properties do not rule out the suitability of these fine dredged sediments for use in geotechnical construction, such as, roa

Therefore, DCPT is a testing technique with short test period, light weight of equipments, and low cost. The DCPT-Nd obtained during the DCPT test is a continuous data to improve the discontinuous SPT-N. Meanwhile, a specified sampler can be applied to have in-situ soil samples and is different from the CPT that unable to have in-situ sample. Thus, the DCPT can be a useful tool for the numerous geologic dete

The soil–bedrock interface is also a crucial boundary affecting slope stability and hydrological dynamics. Therefore, obtaining complete information on underground soil structures would improve the grading of land utilization and the evaluation of potential landslides. Generally, the soil–bedrock interface is believed to be the potential destruction location in shallow landslides; however, few empirical studies validated this hypothesis. Furthermore, p
