✦ Synopsis

An examination of the effects of frictional heating of pore fluid in relation to long-term slope stability is presented. It is found that increases in pore-fluid pressure due to heat-induced expansion may act to enhance creep rates and possibly lead to total loss of stability. Conditions for total stability loss arc examined and an approximate critical value ofaverage shear stress is determined. This value must be exceeded for a sufficiently long period of time in order to induce rapid failure.

This paper further examines the possibility of modelling landslide as a consequence of the unstable slip in a steadily creeping slope when it is subject to perturbations, such as those induced by rainfall and earthquakes. In particular, the one-state variable friction law used in the landslide analy
