【摘要】 本文用有限元方法研究了鲜水河断裂带的地震迁移,分析了炉霍7.9级地震和道孚6.9级地震迁移过程中应力、应变能和安全度G值的变化及其与未来地震危险地段的关系。计算结果表明该断裂带未来地震危险地段为“道孚—乾宁”。更多还原

【Abstract】 In this paper, the finite element is used to study earthquake migration along Xianshuihe fault. The relationship between variations of stress,strain energy and safety G-values during the migration process of Luhuo earthquake (M=7.9) to Daofu earthquake (M=6.9),and a dangerous segment with future earthquake has been analysed in the paper. Tne results from calculation suggest that the dangerous segment with future earthquake along the fault is Daofu-Qianning segment.更多还原
