A group of lithologies which includes claystone, siltstone, mudstone and shale also known as mudrocks are indurated sediments widely encountered throughout the world. Shear strength and deformation characteristics of mudstone were investigated using a fully automated hydraulic stress path testing system under three rock states: dry, short-term inundated, and long-term. It is observed that the maximum...
In this paper, the authors studied the deformation and shear strength behavior of an argillaceous siltstone used as rockfill material for the 261.5m high Nuo Zha Du core wall rockfill dam in south-western China. As the soft siltstone was poorly cemented and easily disintegrated on exposure to water, it was considered to be susceptible to weathering. The long term behavior of rockfill is of major concern...
