中文摘要:
      针对地震发生后亟需对土石坝群体震害进行快速评估的问题,基于统计数据和MSA方法,提出了土石坝群体震害易损性分析方法。通过分析土石坝群体震害数据,对震损大坝进行等级划分,结合地震破坏损失比和破坏比建立土石坝地震易损性矩阵。并引入MSA方法,建立土石坝群体震害易损性评估模型,计算出四种烈度下易损性参数及易损性曲线和概率,为土石坝群体震害快速评估提供了依据。
英文摘要:
      It is urgent to evaluate the seismic damage of group earth rockfill dams after earthquake. Based on the statistical data and multiple stripe analysis (MSA) method, the seismic fragility method of group earth rockfill dams was proposed. According to the analysis of seismic damage data of earth rockfill dam, the seismic damage level was classified. The seismic fragility matrix of earth rockfill dam was established based on the loss ratio and damage ratio of earth rockfill dam. The MSA method was applied to establish the fragility assessment model of group earth rockfill dam after earthquake. The fragility parameters of four kinds of intensity were calculated, and the related fragility curves and damage probability were obtained, which provides the basis and reference for the rapid evaluation of the earthquake damage of group earth rockfill dam.
