一、引言作者曾在中国迁西地区岩样中测到了古构造残余应力,之后在该区垂直和平行迁西山字型的构造带内布设了11条测线共68个测点.以岩体正交异性弹性理论为基础,选取所测矿物的轴面异性弹性参量.用X射线法,测得了岩体水平和铅直宏观残余应力分量的大小和方向及其水平分布场,嵌镶残余应力的水平分布场,以及这两种残余弹性应变能密度的水平分布场.同时鉴定了此种场形成的地质时代,算出了山字型构造带中储存
I. INTRODUCTION The authors have measured residual tectonic stress in the rock samples from the Qianxi area, China, and then laid 11 measuring lines with a total of 68 measuring points in the vertical and parallel Xishan font type tectonic belt in this area. Orthogonal anisotropy theory, the axial anisotropy elastic parameters of the measured minerals are selected.Using X-ray method, the size and direction of the rock mass and the vertical macro-residual stress components and the horizontal distribution of the residual stress Horizontal distribution field and horizontal distribution field of these two kinds of residual elastic strain energy density.At the same time,
