Assessing the Undrained Strength Cross-anisotropy of Three Tailings Types
Author(s) D. Reid* R. Fanni† A. Fourie* Abstract The cross-anisotropic nature of soil strength has been studied and documented for decades, including the increased propensity for cross-anisotropy in layered materials. However, current engineering practice for...
Improving Microbially Induced Calcium Carbonate Precipitation Effects by Nacre Extractions
Author(s) X. Xu* H. Guo* M. Li† H. Fu† Abstract In microbially induced calcium carbonate precipitation (MICP) process, it is the precipitated calcium carbonate that cements loose sand particles together to improve their mechanical properties. Seashell nacre...
Site Response Analysis of Liquefiable Soil Employing Continuous Wavelet Transforms
Author(s) D. Chavan* T.G. Sitharam* P. Anbazhagan Abstract Propagation of the earthquake motion towards the ground surface alters both the acceleration and frequency content of the motion. Acceleration–time record and Fourier amplitude spectrum of the motion...
Effects of Technological Voids and Hydration Time on the Hydro-mechanical Behaviour of Compacted Bentonite/Claystone Mixture
Authors Zhixiong Zeng* Yu-Jun Cui† Nathalie Conil‡ Jean Talandier§ Abstract Pre-compacted MX80 bentonite/Callovo-Oxfordian (COx) claystone mixture has been considered as a promising sealing/backfilling material in deep geological repository for high-level...
3D Fractal Analysis of Multi-scale Morphology of Sand Particles with μCT and Interferometer
Authors Hong-Wei Yang* Sérgio D. N. Lourenço† Béatrice A. Baudet‡ Abstract The particle morphology of granular materials comprises different characteristic scales, including particle shape and surface texture. Different methods have been proposed to...
A Macro-element Model for Predicting the Combined Load Behaviour of Spudcan Foundations in clay overlying Sand
Authors Yifa Wang* Mark J. Cassidy† Britta Bienen‡ Abstract A macro-element model for predicting the load–displacement behaviour of a spudcan foundation in clay overlying sand when subjected to combined vertical, horizontal and moment loading is introduced....
The Behaviour of Bolders Bank Glacial Till Under Undrained Cyclic Loading
Authors Emil Ushev* Richard Jardine† Abstract Analysis of foundation behaviour under repeated loading can be important to the design of offshore facilities, towers, bridges, wind turbines and other structures. Although detailed guidance is available on how some...
Stress–strain Behaviour of Bio-desaturated Sand Under Undrained Monotonic and Cyclic Loading
Author(s) Kangda Wang* Jian Chu† Shifan Wu‡ Jia He§ Abstract 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 triaxial tests was performed on bio-desaturated sand...
Ground Waste Glass–carbide Lime as a Sustainable Binder Stabilising Three Different Silica Sands
Author(s) Nilo Cesar Consoli* Mariana da Silva Carretta* Lucas Festugato* Helena Batista Leon* Lennon Ferreira Tomasi* Karla Salvagni Heineck* Abstract Waste glass is a solid residue usually available near urban centres, where it is discarded after being used...
