Embankment Stability

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.

The Stability

The stability of reservoir landslide would be influenced obviously by the fluctuation of water level, especially when the water descends, which is different from common landslide. Due to the unsteady seepage of underground water inside slope caused by the change of water level, the stability analysis of reservoir landslide through fluid-solid coupling is very complicated. At present, most people hold the view qualitatively that the less the permeability coefficient is and the faster the water level changes, the more unfavorable it is to the stability. This view lacks quantitative basis. Based on FEM strength reduction, the paper analyzes the influence of different sets of descending speed and permeability coefficient on the stability of reservoir landslide through fluid-solid coupling analysis. The paper also conducts the relevant analysis on the change of the characteristics of seepage field inside the slope, which provides basis for the study of the failure mechanism and the forecast of reservoir landslide.
