Journal ArticleDOI
Geometric anisotropy modeling and shear behavior evaluation of graded crushed rocks
TL;DR: In this article, a numerical technique was proposed to simulate the geometric anisotropy of the graded crushed rocks (GCRs) using randomly generated models, and studies on meso-mechanical responses during the loading were performed through the biaxial shear test and California bearing ratio (CBR) test.
Journal ArticleDOI
Effects of Gravel Content and Shape on Shear Behaviour of Soil-Rock Mixture: Experiment and DEM Modelling
TL;DR: In this article, the influence of gravel content and shape distribution of limestone and basalt gravels on the shear strength of soil-rock mixture (SRM) at various stress conditions was evaluated.
Journal ArticleDOI
Modeling humidity and stress-dependent subgrade soils in flexible pavements
TL;DR: In this paper, a finite element model was developed to simulate the flexible pavement structure by considering the nonlinear characteristics of subgrade soils which are related to humidity and stress, and a UMAT was programmed to characterize nonlinear moisture and stress-sensitive relationship of sub grade soils.
Journal ArticleDOI
Characterisation of stress and moisture-dependent resilient behaviour for compacted clays in South China
TL;DR: In this article, a logarithmic function between the soil suction and resilient modulus was built and a new variable named the minimum bulk stress was defined to separate the shear effect of soil samples from the bulk stress.
