Shear strength of interface between high-performance concrete and claystone in the context of a French radioactive waste repository project

期刊: GEOTECHNIQUE, 2021; 71 (6)

The Callovo-Oxfordian (COx) claystone is chosen as a potential geological barrier for the geological repository of radioactive waste in France, and hi......

Application of an acoustic emission source-tracing method to visualise shear banding in granular materials

期刊: GEOTECHNIQUE, 2021; 71 (10)

The acoustic emission (AE) technique can be used to locate failure-induced AE sources and provides an alternative to continuously visualise the develo......

Model-independent strength-reduction factor for effect of spatial variability on tunnel with improved soil surrounds

期刊: GEOTECHNIQUE, 2021; 71 (5)

Spatially variable cement-treated ground can be considered, in design, as a uniform medium with appropriately reduced strength. Various strength reduc......

Hyperbolic spiral model for predicting reverse fault ruptures in sand based on centrifuge tests

期刊: GEOTECHNIQUE, 2021; 71 (7)

Fault deformation can cause severe damage to structures located within the fault zones. A logarithmic spiral model was developed by D. A. Cole and P. ......

Influence of failure mechanism on seismic bearing capacity factors for shallow foundations near slopes

期刊: GEOTECHNIQUE, 2021; 71 (7)

The bearing capacity of shallow foundations may decrease when located near slopes, particularly under seismic conditions. However, there is limited wo......

DEM modelling of mini-triaxial test based on one-to-one mapping of sand particles

期刊: GEOTECHNIQUE, 2021; 71 (8)

This paper presents a discrete-element method simulation of mini-triaxial tests on a sand with realistically shaped grains. It compares the results wi......

Quantitative shear strength-consolidation stress-void ratio interrelations for reconstituted clays

期刊: GEOTECHNIQUE, 2021; 71 (10)

Isotropically and anisotropically consolidated undrained triaxial compression shear tests are conducted on 87 specimens of eight kinds of clays recons......

Stress-strain behaviour of bio-desaturated sand under undrained monotonic and cyclic loading

期刊: GEOTECHNIQUE, 2021; 71 (6)

Microbial (or bio-) desaturation is a new method for mitigation of the liquefaction hazard of sand. In this paper, a series of monotonic and cyclic tr......

A centrifuge investigation of the relationship between the vertical response of footings on sand and CPT end resistance

期刊: GEOTECHNIQUE, 2021; 71 (5)

This paper presents results from a systematic investigation of footing response in four different types of sands placed and tested under controlled co......

A multi-phase, multi-component model for coupled processes in anaerobic landfills: theory, implementation and validation

期刊: GEOTECHNIQUE, 2021; 71 (9)

To describe the long-term coupled behaviour of landfilled municipal solid waste (MSW), this paper proposes a numerical model based on the theories of ......

A new physically based impact model for debris flow

期刊: GEOTECHNIQUE, 2021; 71 (8)

A new analytical model is proposed to estimate the peak impact pressure of debris flow exerted on a rigid barrier. The new model consists of two terms......

Sensitivity analysis and seepage/leakage monitoring using point heat source

期刊: GEOTECHNIQUE, 2021; 71 (10)

Seepage monitoring is an important issue in the health monitoring and performance evaluation of geotechnical engineering, and one of the effective way......

Optimising the hydrophobicity of sands by silanisation and powder coating

期刊: GEOTECHNIQUE, 2021; 71 (3)

Sands are naturally hydrophilic granular materials, yet, rendering them hydrophobic could lend them to a wide range of geotechnical applications. This......

Cyclic normal load-displacement behaviour of clay-coated sand grain contacts

期刊: GEOTECHNIQUE, 2021; 71 (3)

A micromechanical experimental study is presented in this paper investigating the normal contact response of quartz sand grains under cyclic loading. ......
