中国西南部强震带残余应变能水平场与大震分布的关系
Relation between Residual Strain Energy Horizontal Field and Large Earthquake Distribution in Strong Seismic Belts in Southwestern China

据岩体正交异性弹性理论,横跨与平行龙门山断裂带,安宁河断裂带、红河断裂带和鲜水河断裂带四个测区,用X射线法布设26条测线,测得了岩体宏观残余应变能密度水平分布等值线图,研究了其与区内大震时空分布的关系。
Based on the theory of elasticity for orthotropic rock mass, using X-ray diffraction method, 26 survey lines were laid across and along four fault zones, including Longmenshan fault, Anninghe fault, Honghe fault and Xianshuihe fault zone. Then the density horizontal distribution isoline for macro-residual strain energy of rock mass was drew and the relationship between it and spatial-temporal distribution of large earthquakes in these study areas was studied.
