The pressure distribution beneath a conical sandpile, created by pouring sand from a point source onto a rough rigid support, shows a pronounced minimum below the apex (‘the dip’). Recent work of the authors has attempted to explain this phenomenon by invoking local rules for stress propagation that depend on the local geometry, and hence on the construction history, of the medium. We discuss t...

In recent years, artificial neural networks (ANNs) have been applied to many geotechnical engineering problems and have demonstrated some degree of success. In the majority of these applications, data division is carried out on an arbitrary basis. However, the way the data are divided can have a significant effect on model performance. In this report, the relationship between the statistical pr...

The aim of the study was to characterize a variety of microstructure development-levels and geotechnical property sequences of the late Pleistocene-Holocene deposits in the Mekong River delta (MRD), and the paper furthermore discusses the influences of delta formation mechanisms on them. The survey associated the geotechnical engineering and the sedimentary geology of the late Pleistocene-Holoc...

The spheropolyhedra method has been used earlier for efficient and accurate molecular dynamics simulations of granular matter with particles with complex shapes. Also the Voronoi construction is a tool of proved utility for the virtual representation of powders and grains. In this paper a technique that combines the two methods and provides a framework for the study of the three-dimensional mec...

Various earth-retaining structures are extensively used in different civil engineering projects. Using the results of experimental and numerical modeling, effect earthquake loading on distribution earth lateral pressures basement walls was investigated. The UBCHYST constitutive model performed simulations, using 12 centrifuge dynamic tests, a calibration process conducted to obtain proper input...

Recent ground failure case histories after 1994 Northridge, 1999 Kocaeli and 1999 Chi-Chi earthquakes revealed that low-plasticity silt-clay mixtures generate significant cyclic pore pressures and can exhibit a strain-softening response, which may cause significant damage to overlying structural systems. In this study, results of cyclic tests performed on undisturbed specimens of ML, CL, MH and...

This paper forms part of the SINEW (sinkhole early warning) project and continues work conducted by Möller co-workers in 2022, where 1g experiments demonstrated feasibility using distributed fibre-optic sensing (DFOS) for sinkhole warning. Their experimental campaign highlighted an order magnitude difference strain between soil cable that remains unexplained weakens confidence technology and/or...

The combined influence of density and stress-induced fabric anisotropy on the nature stress transmission in gap-graded soils with cohesionless fines has been explored using discrete element method (DEM). Various particle size ratios contents were considered simulations constant mean triaxial compression. Analysis available particle-scale data focused understanding how was distributed among betw...

This contribution tackles the issue of incipient conditions for initiation erosion by a fluid flow at surface cohesive materials. To this end, typical assessment procedure consists subjecting soil sample to progressive hydrodynamic stresses induced submerged impinging jet whose injection velocity is gradually increased. paper presents results an extensive use protocol both in experiments and nu...
