震害面积的多因素灰色关联分析

GREY INCIDENCE ANALYSIS OF FACTORS AFFECTING ISOSEISMAL AREA

  • 摘要: 本文应用灰色系统理论,根据云南37个历史地震资料,分别按震害区烈度的高低、断裂文汇程度的强弱组成若干子系统。各子系统中部以震害面积作为参考数列,以震级、震源深度、断裂文汇程度作为比较数列,对震害面积进行了多因素灰色关联分析,排出了关联序。研究结果客观地揭示出震害面积与各影响因素即震级、震源深度、断裂交汇程度之间的相互关系,为进一步研究震害面积的定量计算提供了依据。

     

    Abstract: In this paper, several subsystems are formed according to the intensity level and the degrees of active fault intersection respectively in earthquake disaster areas by grey system theory and 37 earthquake records of Yunnan province. In every subsystem, the isoseismal area, the magnitude, focal depths and the level of the active fault intersection have been recognized as the referring series and comparing series respectively. Then, the grey incidence analysis of the factors affecting isoseismal area and the order of incidence have been made. The results have shown the relation between the isoseismal area and factors affecting it, such as the magnitude, focal depths and level of the active fault intersection, and provided a basis of the future research for the quantitative estimation of the isoseismal area.
