Abstract 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 are examined and an approximate critical value of average shear stress is determined. This value must be exceeded for a sufficiently long period of time in order to induce rapid failure.
