| 摘 要： | 结合三峡工程永久船闸陡高边坡特点，将高边坡岩体简化正交异性体，在对高边坡岩体开挖卸荷非线性力学特性充分认识的基础上，提出了各向异性非线性卸荷岩体的力学分析方法－变刚度分析理论，其计算成果与现场观测成果有的一致性。对三峡工程永久船闸陡高边坡岩体开挖分析表明高边坡岩体将产生较大的变形，与以往研究成果有数量级的差别。

| Abstract: | According to the characteristics of the shiplock high slope of Three- Gorges Project, this paper simplified the rock mass of the high slope as orthogonally anisotropical media.On the basis of recongnizing the nonlinear mechanics of excavation unloading,the paper prsents the nonlinear mechanics calculating method ,the theory of changing stiffen analysis. The calculating results agree fairly close to the measured one.By the excavating calculation of shiplock high slope, the paper shows that the rock mass will produce the large deformations,which have the large difference with the results of the old studies |
