Production of gaseous pore pressure during rock slides
Tóm tắt
When a rock mass slips, the local heating of the slip surface transforms pore water into vapour if the surface of failure is deep enough. It is possible to calculate, as a first approximation, a critical displacement of the mass necessary to create vapour in the slide zone. A second approximation gives the relation between critical displacement and rate of shear displacement as the slide mass creeps towards catastrophe.
