摘要
以岩体正交各向异性弹性理论为基础,用X射线衍射法,沿红河断裂带布设7条测线,沿迁西山字型构造带布设11条测线,完成了岩体中三维残余应力测量,绘出了宏观残余应力场等值线及主应力线图、微观残余应力场等值线图,算出了岩体内两种残余弹性应变能密度场,确定了其形成时期。
This treatise has accomplished resid(?)l stresses measurement of three dimensions in rock masses in Honghe fracture zone and Qianxi epsilon-shaped structural system, has drawn isopleth and principal stressline maps of macro--residual stressos as well as isopleth map of micro--residual stresses, has evaluated elastic strain energy density fields of aforesaid two kinds of residual stresses in rock masses in these regions and has determined their formed periods. The measurement has been based on orthotropic elastic theory of rock mass and used the x-ray diffraction method.
