摘要
地铁盾构隧道中的渗漏水问题不仅会破坏地铁线路,还会引起隧道变形等病害.为探究地铁盾构隧道渗漏水原因,建立科学有效的防范措施,以现场调研为基础,结合网络层次分析法与灰色模糊综合评价法,通过分析渗漏水原因,构建盾构隧道渗漏水风险指标体系,建立基于ANP的灰色模糊综合评判模型,并以郑州某地铁区间项目为例,对盾构隧道渗漏水进行综合评价.结果表明:盾构隧道渗漏水的主要影响因素包括密封垫老化和不良的地下水环境及隧道覆水深度.所建立的评价模型能够准确评估城市地铁盾构隧道工程的渗漏水风险,为城市地下交通渗漏水风险的综合评估提供了一种新的思路和方法.
Abstract
Leakage of water is a common issue in subway shield tunneling which not only damages the subway infra-structure but also leads to tunnel deformation,resulting in disruptions to train services.Moreover,water leakage can exacerbate the development of other tunnel-related issues,creating a chain reaction of impacts.Therefore,to thor-oughly investigate the causes of water leakage in subway shield tunnels and establish scientifically effective preventive measures,based on on-site investigations,this work combines the Analytic Network Process(ANP)with the Grey Fuzzy Comprehensive Evaluation Method to analyze the reasons for water leakage by constructing a risk indicator system for shield tunnel water leakage and establishing a Grey Fuzzy comprehensive evaluation model based on ANP.Zheng-zhou subway section project was taken as an example to comprehensively assess water leakage in shield tunnels.The results indicate that the main influencing factors of water leakage in shield tunnels include seal pad aging,adverse groundwater conditions,and tunnel cover water depth.The evaluation model established is capable of accurately asses-sing the water leakage risk in urban subway shield tunnel projects,providing a new approach and method for the com-prehensive assessment of water leakage risks in urban underground transportation.
