摘要：
Based on Simplified Bishop Slice Method and by applying LHS -MC method, risk analysis of slope instability in earth dams is presented. Based on Bishop Model, the equilibrium equation is established to evaluate the slope instability risk accounting for the uncertainties arising from soil properties and water level. Cohesive force c, friction angle phi, their relation and water level are taken as random variables which have a large influence on slop instability. One example of risk analysis for dam slope instability is presented to demonstrate the validity and capability of the proposed method.
