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.
