| 摘 要： | 以高拱坝的极限受务过程中的破坏机制为基础，探讨了拱坝弹性应力状态，非线性状态，流变状态和失稳变形的极限状态，总结了若干高拱坝分析的结果，建议以地质力学模型的破坏试验有限元分析方法以及相应的稳定性评价准则，采用点，面安全度方法评价稳定。

| Abstract: | On the basis of destruction mechanism in the limit loading process of high arch dam several states,such as elastic stress,nonlinear,rheologic and limit state of unstable deformation are approached.The anlysis result of sveral large arch dams is summarized.Their stability is evaluated through destruction tests on geomechanic model,finit element analysis method and relevant stability evaluation criteria by using point and surface safety methods. |
