Abstract: In this study, model pile tests were carried out in a custom-made pressurized chamber to explore the mechanisms of a driven pile setup in dry sand. A bender element system and tactile pressure sensors were used in parallel ...

Abstract: In this paper, the results of a series of experiments using one-dimensional oedometer testing, mercury intrusion porosimetry (MIP), and scanning electron microscopy are reported on kaolinite samples with known and controlled ...

Abstract: In this paper, experimental studies using a true triaxial apparatus and a bender element system, and numerical simulations based on the discrete element method (DEM) were used to investigate the stress- and fabric-induced ...

Abstract: In this study, the effects of cementation on the stress–dilatancy and strength of cemented sand are investigated through experimental characterizations using triaxial tests and numerical simulations using the discrete ...

Abstract: Two commonly encountered saprolitic soils in Hong Kong, weathered volcanic tuff (WT) and weathered granite (WG), were studied using high-quality intact samples. The intact samples exhibited quasi-preconsolidation pressure ...

Abstract: The stress intensity factor (SIF) corresponding to two collinear cracks emanating from the internal boundary of a tube is calculated by boundary collocation method (BCM). Uniform internal pressure ...

Abstract: This study explored the features of particle motion and, in particular, the associated movements at contacts in response to direct shearing. A tailor-made direct shear box equipped with an image system was set up. The ...

Abstract: This paper reconsiders the signals that are transmitted in bender element tests and the associated transfer functions to identify the problems that bias the velocity (travel time) determination. The findings of the numerical ...
