Abstract: Pullout of plate anchors from granular sands is investigated using a novel computational multiscale approach. We employ the material point method (MPM) to solve a large deformation boundary value problem and adopt the ...

Abstract: Microbiologically induced calcium carbonate precipitation (MICP), as a promising reinforcement technique, has been investigated extensively through element and model tests. However, tests on the particle-scale behaviors ...

Abstract: Shallow landslides often occur in unsaturated soil slopes under seepage conditions. The shear strength of unsaturated soils is one of the key factors in evaluating the stability of these slopes. Due to the high nonlinearity ...

Abstract: This study investigated the performance of microbially induced calcite precipitation (MICP) in reinforcing road bases reconstituted with calcareous or silica sands. Four testing models were prepared by the surface percolation ...

Abstract: Microbially induced calcite precipitation (MICP), a newly green method, was investigated as a possible solution to rainfall-induced erosion of sandy slopes. A series of model slopes prepared with sands of different gradations ...

Abstract: Degradation of geomaterials, that is, particle breakage, can be harmful to the full life-cycle stability of practical engineering; for example, rockfill dam, energy-pile foundation, railway embankment, and retaining wall. ...
