| 摘 要： | 以岩体正交异性弹性理论为基础，用Ｘ射线法，在安宁河断裂带测区，选取了９个钻孔的岩芯，测量了岩体中宏观残余应力场的水平和铅直三维主应力及最大剪应力随深度的分布，分析了其沿深度的分布规律，求得了其铅直梯度值

| Abstract: | Based on the anisotropic elastic theory of rock mass,the X ray method is adopted to measure the 3 D macro residual principal stresses as well as distribution of the maximum horizontal and vertical shear stresses with depth in rock mass from 9 measuring boreholes in Anninghe fault zone.The regularities of the distributions are analysed and the vertical gradient values are obtained. |
