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”。
In this paper, the finite element method was used to study the seismic migration of the Xianshuihe fault zone. The changes of stress, strain energy and safety G values during the migration of the MS7.0 Huohuo MS7.0 Earthquake and the Daofu M6.9 Earthquake were analyzed, Relationship. The calculation results show that the future earthquake risk zone of the fault zone is “Daofu - Ganning”.
