HiStudy on the stability of road embankment due to the effect of water level changes on the slopes

Abstract

This paper presents a study on the stability of road embankment due to the effect of water level changes on the slope. Two scenarios of the drawdown were considered. The first one is the case of the embankment with the water on one slope and the second one is for the embankment with the water on both two slopes. For the two cases, the water level on one side drops. Effects of various parameters such as the permeability of the road embankment soil, the rate of change in water level on the stability of the slope were evaluated, to found out the principle of the change of stability of the embankment. The results showed that the embankment stability reduces if there is a drawdown of the water level on the slope.
