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,沿横过和平行断裂带的6条测线,测量了岩体三维宏观残余应力,绘成了宏观残余应力场水平和铅直三维主分量水平分布等值线图、水平和铅直最大剪应力水平分布等值线图及水平主应力线图,研究了此种场对大地震的控制作用。
This treatise has discussed the three-dimensional macro-residual stress measurement in rock masses along Anninghe fault zone. The isopleth maps of three-dimensional principal stresses, horizontal and vertical major shear stresses as well as horizontal principal stress line map of macro-residual stress field in rock masses in this region are compiled. Also, the controlling process of these fields on large earthquakes in this region is discussed. Based on orthotropic elastic theory of rock mass, the X-ray diffraction method is used in the measurement.
