龙门山断裂带测区古构造残余应力场对大地震的控制
|
摘要
<正> 一、引言地壳岩体古构造残余应力测量,已在中国、美国、日本、英国、葡萄牙和澳大利亚等许多国家开展起来. 本课题,在龙门山断裂带1.1×10~5km~2范围内,用X射线法,以岩体正交异性弹性理论为基础,选测了岩体中力学性质呈高级轴对称的矿物石英和方解石,进行了宏观残余应力测量,绘成最大、最小水平和铅直主应力水平分布等值线图、最大水平和铅直
This treatise has accomplished macro-residual stresses measurement of three-dimensions in rock masses in the range along the Longmenshan fault zone, drawn isopleth maps of three-dimensional principal stresses, horizontal and vertical major shear stresses and elastic strain energy density as well as horizontal principal stress line map of macro-residual stress field in rock masses in this range and studied the control of these fields on large earthquakes in this range. Based on orthotropic elastic theory of rock mass, the X-ray diffraction method is used in the measurement.
