本文以云南地震地质为背景,定义出活动断裂交汇程度作为影响地震震害面积的定量指标,并应用模糊信息处理方法,分析了云南39个历史地震资料,推导出震级、震源深度、断裂交汇程度与震害面积之间的模糊关系,然后研究震源深度为15,25公里时的震级、震害面积关系。文章结论指出:在活断裂密集的高烈度区,断裂分布情况具有影响震害面积的重要作用。此项研究结果,对高烈度区的工程抗震设防范围考虑,具有一定指导意义。
Based on the earthquake geology in Yunnan Province, the definition of the intersection of active faults is a quantitative index that affects the seismic damage area. By using the fuzzy information processing method, 39 historical seismic data in Yunnan are analyzed, and the relationship among magnitude, source depth, And the area of seismic damage, and then study the relationship between the magnitude and the area of seismic damage when the focal depth is 15 and 25 km. The conclusion of the article points out that the distribution of fracture has an important effect on the area of seismic damage in areas with high active densities. The result of this study is of guiding significance for considering the range of seismic fortification in high intensity areas.
