Mineral–water interactions and their influence on the physical behavior of highly compacted Na bentonite
Canadian Geotechnical Journal - Tập 19 Số 3 - Trang 381-387 - 1982
Roland Pusch
Na bentonite is the active component of one of the engineered barriers that are being considered in Sweden to surround the final disposal sites of radioactive wastes from nuclear reactors. It has been chosen because of its low permeability and ion diffusivity and of its self-healing ability through swelling. These properties are due to mineral–water interactions that yield a microstructur...... hiện toàn bộ
Empirical modeling of the compaction curve of cohesive soils
Canadian Geotechnical Journal - Tập 38 Số 1 - Trang 29-45 - 2001
Imad A. Basheer
Compaction curves (or density–moisture relationships) of cohesive soils are essential components for establishing practical and reliable criteria for effective control of field compaction. In this paper, modules built from empirical models for simulating the compaction curves of cohesive soils based on easily measured basic soil properties and compaction energy were developed using both st...... hiện toàn bộ
A method for evaluating the representative elementary volume based on joint survey of rock masses
Canadian Geotechnical Journal - Tập 25 Số 3 - Trang 440-447 - 1988
Masanobu Oda
The representative elementary volume of a statistically homogeneous rock mass is defined as the minimum volume beyond which any submass behaves essentially like the whole rock mass. A simple, but still general, method for the determination of the minimum volume is given on the basis of the crack tensor concept; it is concluded that the size must be at least three times larger than a typic...... hiện toàn bộ
Effect of variable confining pressure on cyclic behaviour of granular soil under triaxial tests
Canadian Geotechnical Journal - Tập 54 Số 6 - Trang 768-777 - 2017
Qi Sun, Yuanqiang Cai, Jian Chu, Quanyang Dong, Jun Wang
Previous studies were performed to use combined cyclic deviatoric stress and confining pressure to simulate cyclic vertical and horizontal normal stresses under traffic loading. The effect of variable confining pressure (VCP) on the permanent deformation of soils was investigated. However, some studies concluded VCP could promote the development of permanent deformation compared to the te...... hiện toàn bộ
Confining stress and static shear effects in cyclic liquefaction
Canadian Geotechnical Journal - Tập 38 Số 3 - Trang 580-591 - 2001
Y. P. Vaid, James David Stedman, S. Sivathayalan
Liquefaction resistance of a sand under cyclic loading is assessed and the effects of the levels of confining pressure and static shear on resistance to liquefaction are investigated. Site-specific values of the resistance under specified levels of confining and static shear stresses are measured in the laboratory. The measured values are compared with those which would be predicted by the...... hiện toàn bộ
Swelling and softening behaviour of La Biche shale
Canadian Geotechnical Journal - Tập 35 Số 2 - Trang 206-221 - 1998
R. V. C. Wong
Free swell, semiconfined swell, and one-dimensional oedometer swell tests were performed on La Biche shale specimens in solutions of different salinities. The swelling behaviour of La Biche shale was found to be highly anisotropic and dependent on electrolyte concentration, stress, and swelling history. Drained triaxial compression tests were conducted on La Biche shale specimens subjecte...... hiện toàn bộ
Evaluation of geotechnical property variability
Canadian Geotechnical Journal - Tập 36 Số 4 - Trang 625-639 - 1999
Kok‐Kwang Phoon, Fred H. Kulhawy
To evaluate geotechnical variability on a general basis that will facilitate the use of reliability-based design procedures, it is necessary to assess inherent soil variability, measurement error, and transformation uncertainty separately. The inherent variability and measurement error are addressed in a companion paper, and transformation uncertainty is addressed herein. A second-moment p...... hiện toàn bộ
Characterization of geotechnical variability
Canadian Geotechnical Journal - Tập 36 Số 4 - Trang 612-624 - 1999
Kok‐Kwang Phoon, Fred H. Kulhawy
Geotechnical variability is a complex attribute that results from many disparate sources of uncertainties. The three primary sources of geotechnical uncertainties are inherent variability, measurement error, and transformation uncertainty. Inherent soil variability is modeled as a random field, which can be described concisely by the coefficient of variation (COV) and scale of fluctuation....... hiện toàn bộ
Numerical back-analyses of greenfield settlement during tunnel boring
Canadian Geotechnical Journal - Tập 50 Số 2 - Trang 145-152 - 2013
Gima V. Mathew, Barry Lehane
This paper examines the potential for two-dimensional (2D) and three-dimensional (3D) finite element (FE) analyses to calculate the ground displacement patterns observed at a greenfield site above two recently completed tunnels in Perth, Western Australia. The influence of a range of different factors on the shape of the tunnelling-induced settlement trough is examined using the Plaxis FE...... hiện toàn bộ
Effect of embedment on consolidated undrained capacity of skirted circular foundations in soft clay under planar loading
Canadian Geotechnical Journal - Tập 54 Số 2 - Trang 158-172 - 2017
Cristina Vulpe, Susan Gourvenec, Alexander F. Cornelius
The effect of foundation embedment ratio and soil–skirt interface roughness on the consolidated undrained capacity of skirted circular foundations under planar loading in normally consolidated clay has been investigated through coupled three-dimensional finite element analyses. Results are presented as failure envelopes, and changes in shape and size of the normalized vertical–horizontal–...... hiện toàn bộ
