Shear strength of geosynthetic composite systems for design of landfill liner and cover slopes
( Elsevier , 2011 , Article)Torsional ring shear tests were performed on composite specimens that simulate the field alignment of municipal solid waste (MSW) landfill liner and cover system components. Simultaneous shearing was provided to each test ... -
Bearing Capacity and Settlement of Skirted Shallow Foundations on Sand
( American Society of Civil Engineers (ASCE) , 2013 , Article)The behavior of axially loaded skirted shallow foundations resting on sand was studied using an extensive numerical analysis. Surface, pier, and skirted square foundations resting on sand with different shear strength ... -
A technique for estimating permeability of a randomly fractured rock mass
( Springer Verlag , 2007 , Article)Extensive field and laboratory testing programs were performed to develop a relationship between the permeability of a fractured limestone and the core recovery values. The studied limestone does not encompass any jointing ... -
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 ... -
Factors influencing determination of shale classification indices and their correlation to mechanical properties
( Springer Verlag , 2006 , Article)The influence of sample preparation procedure on the measured classification indices such as clay-size fraction, liquid limit, and plastic limit of shales was investigated. Shale samples covering a wide range of composition ... -
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 ... -
Numerical study on settlement of piled foundations on homogenous rock
( Taylor and Francis , 2014 , Conference Paper)Settlement behavior of piled foundations on homogenous rock was investigated using an extensive three-dimensional finite element analysis of different piled-foundation models. Effects of pile slenderness ratio, pile spacing, ... -
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 ... -
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 ... -
Macro-scale direct shear test device for assessing soil-solid interface friction under low effective normal stresses
( ASTM International , 2014 , Article)The paper describes a new macro-scale direct shear test device for assessing the largedisplacement soil/solid interface drained shear strength at low effective normal stresses. The testing method arises from a need to ... -
Simple Procedure for Preliminary Estimation of the Permeability of Randomly Fractured Rock Masses
( American Society of Civil Engineers (ASCE) , 2024 , Article)A data-driven approach is used to show the significant discrepancy between the coefficients of permeability that are estimated through packer field tests and those back-calculated from the actual discharge pumped out of ... -
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 ... -
Comparison of site-specific and empirical correlations for drained residual shear strength
( ICE Publishing , 2020 , Other)The discusser has an interest in the topic of the paper (Hayden et al., 2018) on the ability of empirical correlations to predict the residual friction angle of samples from a specific site. In fact, he provided one of 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, ... -
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 ... -
Estimating the permeability of fractured rock masses for design of construction dewatering systems
( Elsevier , 2023 , Article)A comprehensive data on dewatering and pumping-well systems installed in fractured rock is compiled and analyzed to estimate the permeability of fractured rock masses. The data covers construction activities of different ... -
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 ... -
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 ... -
A first look at whale sharks in Hawaiian waters: Using citizen science to study the world's largest fish, Rhincodon typus
( John Wiley and Sons Ltd , 2023 , Article)The world's largest fish, the whale shark (Rhincodon typus), is a circum-tropically distributed and globally endangered species, that is widely studied at predictable aggregation sites. The main Hawaiian Islands are not ... -
Interactions between marine megafauna and plastic pollution in Southeast Asia
( Elsevier B.V. , 2023 , Other)Southeast (SE) Asia is a highly biodiverse region, yet it is also estimated to cumulatively contribute a third of the total global marine plastic pollution. This threat is known to have adverse impacts on marine megafauna, ...
