【摘要】 在水电工程建设中,我们经常会遇到各种各样的变形岩体,其中最常见的莫过于岩体的卸荷变形和倾倒变形。当工程的关键部位同时存在这两种岩体变形时,成因机制分析和稳定性评价则显得至关重要。本文主要以乌弄龙水电站工程实例来分析岩体岸坡复杂的变形机制,结合变形岩体的工程特性选取力学参数,并对变形岩体进行了稳定性评价,认为该处变形由多因素地质作用共同造成,经过野外调查、室内测试和分析计算,得到其在各种工况下的稳定性。更多还原

【Abstract】 At the hydroelectricity engineering construction,we always meet all kinds of the deformation rock,such as the familiar unloading and toppling deformation of the rock.It is very important that the mechanism analysis and the stability evaluation When the two kinds of the deformation rock occurred in the key place of the one engineering.This paper discussed the methods of the mechanism analysis and the stability evaluation for the complex deformation rock with a engineering example of the Wunonglong hydropower station.The results indicate that the deformation is caused by a combination of the many geological factor.The stable state of each situation is gained through field investigation,experimental analysis and numerical simulation.更多还原
