The Influence of Reservoir Level Plummeting on Slope Stability Reinforced by Pile

Abstract:

Lagrange finite difference method basing on the strength reduction principle is applied to simulate the reinforcement effect of anti-slide pile for slope under water plummeting condition. The influence factors of reinforcement effect including speed of water level plummeting, the ratio between water depth and slope height, the location of pile is discussed. The study results show that the higher speed of water level plummeting may result in less value of slope safety factor. Moreover, the relationship between the ratio between water depth and slope height change significantly before and after reinforcement under water level plummeting condition. The study also reveal that the location of pile have important influence on the reinforcement effect.
