Coupling Elasto-plastic Behaviour of Unsaturated Soils with Piecewise Linear Large-strain Consolidation
Authors: Shunchao Qi* Paul Simms† Farzad Daliri‡ Sai Vanapalli§ Abstract Slurried soils or tailings are often deposited in layers that undergo complex stress paths in terms of desiccation and loading, as a given layer may undergo variable degrees of desiccation...
Load-controlled Cyclic T-bar Tests: A New Method to Assess Effects of and Consolidation
Authors: C. D. O'Loughlin* Z. Zhou† S. A. Stanier‡ D. J. White§ Abstract Full-flow T-bar and ball penetrometer tests are often used to measure intact and remoulded soil strengths, with the latter determined after several large-amplitude displacement cycles. In...
Drained Response of Rigid Piles in Sand under an Inclined Tensile Load
Authors: Ting Huang* Conleth O'Loughlin† Christophe Gaudin† Yinghui Tian‡ Ting Lu† Abstract The response of rigid piles in sand to an inclined tensile load is poorly documented and understood, particularly when the load is cyclic. This is becoming relevant for...
Using FBGS to Estimate the Horizontal Response of a Monopile in a Geotechnical Centrifuge A
uthors: Zhong-Sen Li, PhD Matthieu Blanc, PhD Luc Thorel, PhD Abstract A circular aluminium tube 50 mm in diameter was instrumented with two optical fibres, each of which consists of 13 fibre Bragg grating sensors (FBGS). The performance of the FBGS was evaluated by...
A Method for Cavity Scale Estimation Based on Ground-Penetrating Radar (GPR) Explorations: An Experimental Study
In Seoul, Korea, there have been large and small ground subsidence since 2014, which have become a social issue. Most ground subsidence occurred in the pavement of urban areas, and the main causes are supposed to be the improper construction of water supply pipes,...
