【摘要】 根据对城市地震次生灾害发生机理的分析,绘制了地震次生灾害演化的因果回路图和存量流量图。在此基础上借助系统动力学仿真软件Vensim PLE,对城市地震次生灾害演化过程建立了系统动力学模型,并进行了模型验证及仿真,得出了不同防震抗灾能力下城市地震次生灾害可能造成的损失情况,为城市防震救灾工作提供参考。更多还原

【Abstract】 In this study,the mechanism of the urban seismic secondary disasters was analyzed,and based on this,the causal loop diagram and stock and flow map were drawn,and a system dynamics model of the evolution process of the urban seismic secondary disasters was developed,validated and simulated using the Vensim PLE software.As a result,corresponding loss scenarios caused by seismic secondary disasters in cities with different anti-earthquake capability were obtained to give a reference to strengthening the anti-earthquake work in cities.更多还原
