摘要
基于三峡船闸高边坡的稳定和变形问题的重要性，采用弹．粘弹塑性西原模型，依据监测成果和开挖揭露的地质资料，对边坡岩体力学参数进行了反馈分析．并根据反演分析得到的力学参数，对三峡船闸进行了三维非线性有限元分析，对其稳定性和整体安全储备能力进行了评价。
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.
