| 摘 要： | 从地貌学角度,分析了三峡工程永久船闸边坡岩体的自然及人为卸荷特性,指出了地表侵蚀、河流下切、开挖船闸等自然及人为地貌过程诱发了岩体的基本卸荷过程,构筑了一个三峡工程永久船闸边坡岩体卸荷特性的宏观模式。实地调砥及数值计算成果均表明,地貌分析法在分析实际岩体工程中,岩体卸荷特性方面具有较强的应用价值。

| Abstract: | On the viewpoint of geomorphology, natural and artificial unloading features of rock mass slope in the permanent shiplocks of the Three Gorges Project are analyzed in this paper, which shows that geomorphological processes, e. g. ground erosion, cut of the Changjiang River and artificial cut of the shiplocks etc. have been inducing general unloading features of rock mass in the slope. Unloading features are consistent with characteristics insitu and calculating results using unloading nonlinear FEM method. |
