Structure Evaluation of a Tropical Residual Soil Render Wide Range of Compaction Conditions
Author(s) Bruna de Carvalho Faria Lima Lopes* Vinícius de Oliveira Kühn† Ângela Custódia Guimarães Queiroz‡ Bernardo Caicedo§ Manoel Porfírio Cordão Neto|| Abstract Soil compaction is one of the most common techniques used to engineer the soil. It is especially...
Optimising an Output of a Slip Line Field Using a Chaotic Swamp Optimisation Algorithm
Author(s) Thanh Liem Vo* Thi Ngoc Mac† Duy Minh Do‡ Abstract In solving earth pressure problems, many input parameters are needed to account for more realistic soil properties and complex boundary conditions.Finding an optimal output while considering many...
Snakeskin-inspired Patterns for Frictional Anisotropic Behaviour of Split set Rock Bolts
Author(s) P. Vangla* B. A. Wala† V. L. Gayathri‡ J. D. Frost§ Abstract The study explores the effect of directionally dependent frictional resistances (frictional anisotropy) inspired by snakeskin patterns, on the behaviour of split set rock bolts. The patterns...
Strength Characteristics of Brittle Rocks under Multi-stage intermediate Principal Stress Loading
Author(s) L. Shi* C. C. Li† X. Zhang* X.-T. Feng* G. Wang* Abstract A series of single-stage true triaxial compression (TTC) tests and multi-stage intermediate principal stress (σ2) loading tests were carried out on three types of brittle rock specimens in this...
Loading Transfer Mechanism of a Piled Raft Subjected to Normal Faulting in Sand
Author(s) Q. Cai* B. Xiang C. W. W. Ng† K. S. Wong‡ X. Chen* Y. Zhuang Abstract Although different kinds of foundations have been investigated against an earthquake faulting, the interaction between pile group and dip–slip fault has not yet been fully...
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...
