隧道施工造成的环境损失分析理论在工程保险中的应用研究

城市轨道交通建设中涉及第三者财产损失的事故占有相当比例。近年来，已有较多的工程风险基本理论及风险管理方面的研究成果，然而针对隧道的风险管理却应用较少，特别是基于量化方法的风险分析研究比较缺乏，这导致了工程风险分析和工程保险工作一直缺乏数理分析依据。文章在盾构隧道施工的环境风险分析与工程保险的承保条件评价中使用了量化的方...

Applying the Analysis Theory on Environmental Loss due to Shield Tunnel Construction to Engineering Insurance

A large proportion of accidents in the construction of municipal railroads are related to third-party property losses.In the insurance field,there are many research results on fundamental engineering risk theories and risk management,but few of them have focused on shield tunnel risk management.In particular,there is a lack of comparative risk management researches based on quantitative method.As a result,there is a lack of quantitative data support for engineering risk analysis and engineering insurance.The paper used the quantitative method in the environmental risk analysis and engineering insurance underwriting condition assessment for shield tunnel construction.The Peck Formula has been proved to be a reliable and practicable method to evaluate the settlement of stratum in its cross section while a shield tunnel passes through it.The result it arrives at fit quite well with the actual monitoring result.This method which used in this essay is based on both the Peck Formula and the building destruction membership function theory to judge the third party building′s settlement loss while shield tunnel passes through its stratum.The result can reflect the tendency and scope of actual losses.This offered a fairly simple and practical method to quantitatively study possible upper building settlement losses in the construction of a shield tunnel passing under it.And it can also provide insurance companies with quantitative method to underwriting relevant risks.
