%X In the construction of express highways in mountainous areas in west China,landslide or failure of the mudstone slopes often occur. On the basis of large deformation theory,with the completely nonlinear transient dynamical analysis,the time-dependent deformation process is studied considering pore water pressure produced by downpour before and after excavation and the dissipation of pore pressure. It is revealed that the leading factor affecting slope stability is pore water pressure,which provides a basis for reinforcement measures.
