岩石边坡工程与卸荷非线性岩石(体)力学

ROCK SLOPE ENGINEERING AND UNLOADING NONLINEAR ROCK MASS MECHANICS

提出卸荷非线性岩石力学的概念及其主要内容，指出卸荷非线性岩石力学与加载岩石力学的区别。认为岩石边坡开挖为卸荷条件，以往用加载岩石力学方法不能反映边坡岩体的实际力学状态。采用卸荷非线性岩石力学方法对自然边坡及人工边坡的分析实例表明，计算成果与实际情况吻合。

Unloading nonlinear rock mass mechanics, one new concept in geotechnics, is put forward by the author in this paper, and whose main researching contents are discussed in the paper. The results identify that there is intrinsically distinction between unloading nonlinear rock mass mechanics and normal loading one. The excavation of rock slope is under the unloading conditions, and the loading conditions as before can not manifest the essential features of the slope. According to cases analysis about both natural and artificial cut rock slopes in unloading nonlinear rock mass mechanics, it is discovered that the researching results in this method are well accordant with actual features of rock slopes.
