Abstract:
Soil velocity profile often used as subsurface characterization by using geophysical technic. Seismic refraction is one of geophysical technique to determine primary wave (p-wave) velocity of soil profile. In this paper, seismic refraction technique has been performed on two different types of soft soil (peat soil and RECESS clay) for comparison of its p-wave velocity soil profile. From p-wave velocity soil profile comparison, its show the peat soil has soil velocity range from 211 m/s – 534 m/s at depth of 0 – 4 m while the soft clay show soil velocity range from 248 m/s – 1842 m/s at depth o

Abstract:
Soils with low bearing capacity (soft soils) can cause the collapse of overlying structures. Before the superstructure is built, the soft soil needs to be improved first. Effective methods to improve soft soils include applying vertical drain techniques or using geofoam materials. With vertical drains, such as PVD or sand drains, the soft soil settlement can be controlled, while geofoam can be used as a top layer material on soft soil. The purpose of this research is to investigate the performance of Sand Geofoam Granule Columns (SGGCs) as a vertical drain. These SGGCs consist of sand-geofoam

Abstract:
Piled embankments are increasingly used to construct highways on soft soils. End-bearing piles for supporting embankment exhibit different characteristics for the soil arch developed within the embankments. A numerical analysis was conducted to evaluate the soil stress concentration ratio, pile and soil settlements, pile axial force, negative skin friction (NSF) and location of the neutral plane (NP) during embankment filling and consolidation of soft soils. The results indicate that the stress concentration ratio varies with time and most of the embankment load is born by the pile. The soil p

This paper proposes representative constitutive relationship equations of dredging and reclamation soft soil in Korea. The marine soft soils were sampled at 23 dredged-reclaimed construction sites in the Busan, Gwangyang, and Incheon regions in Korea; then, laboratory tests were carried out. The consolidation property was classified as LL = 60% for Busan and Gwangyang marine soft soil and LL = 30% for Incheon marine soft soil by conducting basic physical property tests and consolidation tests. Busan soft soil showed a slightly higher consolidation settlement property than Gwangyang soft soil.

The construction of road structures on soft soils is prone to structural damage due to the low bearing capacity of the soil under the load imposed by vehicles. Chemical stabilization is a popular method used to increase the bearing capacity of soft soils. This study aims to examine the effectiveness of soft soil stabilization using a mixture of lime, nickel slag, and aluminium hydroxide to enhance soil bearing capacity. The addition of lime as a binding agent is expected to reduce plasticity and increase soil strength, while nickel slag and aluminium hydroxide serve as additives that improve o

Abstract The major issues of building a road over soft soils are low bearing capacity and large settlements. The challenges of road construction on soft soils are enormous, so innovative and environmentally friendly methods are required. Geofoam is a type of lightweight infill material and was already used in Norway in road construction applications in 1972. Using Geofoam reduces compacted fill by 40%, less excavation required and less pulverization of native soil making this a time-saving and economically and environmentally viable solution.

Near surface soils can greatly influence the amplitude, duration, and frequency content of ground motions.

With the aim to understand better the seismic response of soft soils deposits, not susceptible to liquefaction, this study made a comparison between the real seismic response registered in soft soil deposit in the 2011 Tohoku earthquake (Mw=9.1), with the response predicted

Some normally consolidated soft soils manifest strength sensitivity, ie these soil manifest strain softening when shear in an undrained mode. These soils, referred to as sensitive soft soils, have the typical features of strain hardening in drained shearing and strain softening in undrained shearing. The consolidation lines of these soils are also curved (concave upwards) in the semi-log space. However, under high consolidation stress or upon large shearing, these soils re-gain the features of re-constituted soil.

Sinking a caisson tunnel in soft soil is new idea and this new concept could be an alternative method of tunneling in soft soil. The aim of this study is to evaluate geotechnical feasibility of sinking the caisson tunnel to the desired depth at the selected soil profile along tunnel alignment. This caisson tunneling method is proposed to reduce the use of temporary works such as propping of sheet pile walls and increase the ease and speed of construction. Besides, it reduces the disturbance on the nearby structures due to vibration.

Abstract:
There were two main objectives of this research. The first objective was to verify SINTEFs' pipe/soil interaction model test results, on which the A.G.A. Level 2 and 3 soil models are based. The second objective was to quantify the amount of conservatives built into the model equations for stiffer clay soils (above 30 psf shear strength). The original testing (at SINTEF) was done in soft clay soils (30 psf), and extrapolations to stiffer soils were done very conservatively, because data was not available. To accomplish these two objectives, pipe-soil interaction model tests were conducted at T

Abstract:
The purpose of this project was to complete a handbook with practical design procedures for submarine pipeline on-bottom stability. The remaining part of the handbook was primarily a description of the interaction between non-trenched pipelines and the seabed where the pipelines were free to move under environmental loading. The objective of this project was to determine the lateral soil resistance forces on a pipeline moving cyclically during hydro-dynamic loading. To meet the goal, full-scale pipe-soil interaction tests were conducted. The models presented in this report are based on the res

Abstract:
In this paper an isotropic hardening elastoplastic constitutive model for structured soils is applied to the simulation of a standard CPTu test in a saturated soft structured clay. To allow for the extreme deformations experienced by the soil during the penetration process, the model is formulated in a fully geometric non-linear setting, based on: i) the multiplicative decomposition of the deformation gradient into an elastic and a plastic part; and, ii) on the existence of a free energy function to define the elastic behaviour of the soil. The model is equipped with two bonding-related intern

Abstract:
Nous sommes tous confrontés à la maladie mentale à un moment ou à un autre de notre vie, que ce soit personnellement ou par l’entremise d’un membre de la famille, d’un ami, d’un voisin ou d’un collègue. Les problèmes de santé mentale peuvent avoir des répercussions importantes sur le plan individuel, mais ils risquent aussi, par un biais préjudiciable, de « s’infiltrer » en milieu de travail, dans les collectivités, au sein de l’économie et dans l’ensemble de la société, si bien que personne n’en sort indemne. Dans un tel contexte, il importe d’aborder le soutien en santé mentale dans une pers

Abstract:
Construction or detailed evaluation of transportation infrastructure requires site-specific ground motions for input into nonlinear structural models. These site-specific ground motions are generally selected based on the magnitude, distance, and site condition of the recorded ground motion. A preliminary study performed by Slate Geotechnical Consultants found that duration and spectral acceleration are negatively correlated for large-magnitude earthquakes recorded on soft-soil sites (Vs30&lt;360 m/s). This means that if the target spectral acceleration is above average, then the average durat
