| 摘 要： | 本文介绍了测量岩体中三维区域残余应力和嵌镶残余应力及其弹性应变能密度的方法,并给出了鲜水河断裂带上的5个大口径深钻孔岩芯的具体测量结果,分析了鲜水河断裂带古构造残余应力及残余应变能密度沿深度的分布规律。结果表明,残余应力及残余弹性应变能密度均随深度的增加而增大。本文还估算了该断裂带岩体中储存的残余弹性应变能的量级。

| Abstract: | This paper introduced the measurements for three dimensional regional residual stresses, mosaic-residual stresses and their elastic strain energy densities distributing with depth in rock masses in measuring region of Xianshuihe fault zone, analyzed their plumb distributive regular pattern with depth, and computed the residual elastic strain energy stored in rock mass of this fault zone. In the measurement, based on orthotropic elastic theory of rock mass, the X-ray diffraction method is used, and the core specimens of 5 heavy caliber-boreholes are selected. |
