Two- and three-dimensional analyses of translational slides in soils with nonlinear failure envelopes
(
Canadian Science Publishing
, 2010 , Article)
This paper aims to assess the effect of nonlinearity of the soil shear strength envelope on the sliding mass con-figurations and the minimum two- and three-dimensional factors of safety for slopes susceptible to translational ...
Comparative study on the behavior of square foundations resting on confined sand
(
Canadian Science Publishing
, 2009 , Article)
The behavior of shallow foundations resting on laterally and (or) vertically confined sand has been investigated using physical and numerical modeling. The models were designed to simulate the frequently constructed raft ...
Stability analysis and charts for slopes susceptible to translational failure
(
Canadian Science Publishing
, 2006 , Article)
The aim of this paper is to develop two- and three-dimensional stability charts for slopes susceptible to translational failure. An extensive parametric study was conducted using a slope model that is designed to simulate ...
Applicability of construction dewatering techniques for randomly-fractured rock
(
ICE Publishing
, 2024 , Article)
Through analyzing a significant number of case histories, ranges of applications of dewatering techniques for randomly-fractured rock are proposed in terms of the rock mass permeability and the required drawdown. The ...
Undrained interface shear strength of fine-grained soils for near-shore marine pipelines
(
ASTM International
, 2020 , Article)
The peak and residual interface shear strengths for a variety of normally consolidated soils were measured using a torsional ring shear apparatus modified to suit soil and interface testing under the undrained condition, ...
Residual shear strength of fine-grained soils and soil-solid interfaces at low effective normal stresses
(
Canadian Science Publishing
, 2015 , Article)
A laboratory research program was undertaken to study the large-strain shear strength characteristics of fine-grained soils under low effective normal stresses ([1]3-7 kPa). Soils that cover a wide range of plasticity and ...
Laboratory testing of full-scale pipes partially embedded in soil to study soil-pipe interaction of offshore seabed oil and gas pipelines - Initial observations
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
The geotechnical aspect of the design of off-shore oil and gas pipelines is a challenge due to inherent uncertainties in predicting soil-pipe interaction behaviour. Physical modeling is often sought after to gain insight ...
Geotechnical considerations on the design of piled rafts on rock
(
Research Publishing Services
, 2011 , Conference Paper)
This research shows the effect of misestimating the pile spring constant (Kpl) and the modulus of subgrade reaction (Ksg) on design of piled rafts on rock. The high mass stiffness of rock contacting the base of such rafts ...
Fully softened shear strength for soil slope stability analyses
(
American Society of Civil Engineers (ASCE)
, 2017 , Article)
The fully softened shear strengths of soils, mudstones, and shales of different plasticities and gradations were measured at low (10 and 25 kPa), intermediate (50 and 100 kPa), and high (200, 300, and 400 kPa) effective ...
Estimating the elastic settlement of piled foundations on rock
(
American Society of Civil Engineers (ASCE)
, 2015 , Article)
This research introduces a simple method for preliminary evaluation of the elastic settlement of piled foundations resting on rock. Despite a significant number of publications in this area, the present effort is distinguished ...
