摘要 为有效评价管廊安全运营脆弱性程度,本文参考市政工程及地下空间工程类的脆弱性评估,首先,明确综合管廊安全运营脆弱性的含义;其次,基于“压力-状态-响应”(PSR)概念框架构建管廊脆弱性评价指标体系,搭建管廊安全运营脆弱性等级评定物元模型;最后,以北京某运营数年的综合管廊为例,将该评估模型进行实例验证。结果表明基于PSR的改进物元可拓模型适用于管廊安全运营脆弱性等级评定,并可为管廊后期安全运营提供借鉴。 To effectively evaluate the vulnerability of the safe operation of the utility tunnel,this paper refers to the vulnerability assessment of municipal engineering and underground space engineering.Firstly,the meaning of the vulnerability of the safe operation of the utility tunnel is clarified.Secondly,based on the concept framework of"pressure state response"(PSR),the vulnerability evaluation index system of utility tunnel is constructed.Finally,taking a utility tunnel in Beijing which has been in operation for several years as an example,the evaluation model is verified by the example.The results show that the improved matter-element extension method based on PSR is suitable for the vulnerability assessment of the safe operation of the utility tunnel,which can provide reference for safe operation of the utility tunnel in later stage.
