Back Analysis of Shiplocks Slope of Three Gorges Project and Evaluation to Stability and Safety
三峡船闸边坡反分析以及稳定性和整体安全储备能力评价

As for the importance of stability problem of the high shiplock slope of the Three Gorges Project, the back analyses for the mechanical parameters of rock masses are proposed by elestic and visco-elasto-plastic model according to the measured and geologic data. With the obtained parameters, the shiplock is analyzed by 3D nonlinear FEM and the monolithic stability and safety are evaluated.
