摘    要:以岩体正交异性弹性理论为基础,用X射线法,在鲜水河断裂带测区沿7条测线,测量了岩体三维残余应力,绘成区域残余应力等值线图、主应力线图及其应变能密度等值线图,探讨了其对带内大地震的控制作用

关 键 词:三维残余应力场  残余应变能密度场  控震作用  鲜水河断裂带

Abstract:This treatise has accomplished residual stresses measurement of three-dimensions in rock masses in Xianshuihe fault zone, drawn isopleth and principal stress line maps of regional-residual stresses as well as isopleth map of elastic strain energy density field of residual stresses in rock masses in this region and studied the control of this fields on large earthquakes in Xianshuihe fault zone. Based on orthotropic elastic theory of rock mass, the X-ray diffraction method is used in the measurement.
Keywords:Three-dimensional paleotectonic residual stress field  Residual strain energy  Controling on earthquake  Xianshuihe fault zone
