Abstract
In this paper a sensitivity analysis about effects of influencing factors on the stability of soil cut and embankment slopes in field was performed. Slope stability analysis of slopes in field was carried out with dry, rainy and seismic conditions. As results of analyzing the sensitivity of factors for the dry and rainy conditions, effect of cohesion, internal friction angle and unit weight of soil on the stability of cut slope is more critical in the dry condition than in the rainy condition. However, their effects on the stability of embankment slope for both conditions are similar to each other. The horizontal seismic coefficient does also affect the stability within the similar range of values irrespective of dry or rainy conditions. Cohesion and internal friction angle are more dominant factors influencing the slope stability irrespective of dry or rainy conditions than unit weight of soil and the horizontal seismic coefficient.
