... occurs due to bending stresses (Amini et al. 2009). However, another mode of toppling failure, which mainly developed in interbedded hard rock (i.e. sandstone) and soft rock (i.e. mudstone, shale and limestone) slope is very common in Three Gorges Reservoir region (Chen et al. 2004; Dong et al. 2010...

..., a Multiple-step Loading Damage (MLD) model was proposed to simulate ML-TCTswithvariousstresspaths. Two series of ML-TCTs were carried out on a sedimentary soft rock of mudstone. The first series was to determine the geotechnical parameters todescribethe MLD model,andthesecondserieswastoverifythe MLD model...

... with large effective porosity was expected. The stress-strain behavior changed from strain-softening to ductle behavior with high effective confining pressure and the pore pressure increased gradually even after the peak strength for the diatomaceous mudstone. On the other hand, strain-softening behavior...
