摘要
为解决因诸灾害间相互作用导致房屋多灾种脆弱性评估较难实现的问题,提出一种基于修正的Papathoma海啸脆弱性评估(PTVA)模型的多灾种耦合物理脆弱性评估方法。首先根据不同灾种影响下承灾体脆弱性指标的差异性,构建指标体系;然后运用修正的PTVA模型,计算单灾种初始脆弱性指数和耦合后的脆弱性指数,经综合计算后,得到2个综合脆弱性指数;最后以福建某市典型区域为例进行实证分析。研究表明:该方法在多灾种耦合物理脆弱性评估中具有可行性,提高了评估的准确性。
A method was developed for assessing physical vulnerability of building to coupled multihazard based on modified PTVA model.According to differences between vulnerability indicators under different disaster conditions,a multi-hazard physical vulnerability assessment index system was established.Initial single hazard vulnerability indexed and coupling hazard vulnerability indexed were obtained by using the modified multi-hazard PTVA model.Then two comprehensive physical vulnerability indices of the initial and the coupling were calculated respectively.The method was used in a typical area in Fujian Province.The application results show that this method can reflect the similarity and difference between physical vulnerabilities of different buildings to different coupling effects,and can improve the accuracy of multi-hazard physical vulnerability assessment.
