Abstract

In this paper, the simulation results of variation of safety factor with suctions of infinite clay slope under partially saturated condition are presented. The variations of safety factor with matric suction ranging from 1 to 100, 000 kPa are presented. The undrained shear strength, which is a function of matric suction, is back-calculated from the laboratory bearing tests reported by Uchaipichat and Man-koksung (2011). The simulations results show that the safety factor increases with increasing matric suction for all values of slope thickness. The results also show a decrease in safety factor with increasing values of slope thickness.
