Abstract
Tropical countries like Singapore are associated with high relative humidity, high tem�perature, and high amount of rainfall throughout the year. Therefore, fux boundary conditions of slopes are afected by rainwater infltration and evaporation rate. The research aims to examine the stability of a residual soil slope under arid and damp period con�ditions. The actual evaporation was utilized in com�bination with rainfall as fux boundary conditions in the mathematical investigations to study the impact of actual evaporation on the distribution of pore-water pressure and factor of safety variation in residual soil slope. The signifcance level of actual evaporation in the stability analysis of residual soil slope was tested by performing two instances of seepage analysis on a slope subjected to (1) rainfall only and (2) rainfall and estimated evaporation. The data from the feld instru�mentation was compared with pore-water pressure variations in residual soil. It was observed that actual evaporation should be incorporated in the numeri�cal analyses as a fux boundary condition in addition to rainfall loading since both actual evaporation and rainfall have a signifcant efect in generating accurate factor of safety variations and pore-water pressure distribution within soil layers.
