为了取得岩体平面变形,采用最大正切应力标准取得了露天矿边帮破坏时间的上限和下限的评定和蠕动条件的边坡情况。按理想弹性面,解决地下建筑不同构件变形和破坏的课题:包括在
In order to obtain the plane deformation of rock mass, the upper and lower bounds of failure time and the conditions of creep are obtained by using the maximum tangent stress criterion. According to the ideal elastic surface, to solve the deformation and destruction of different components of underground construction project: included
