摘要
为了研究复杂环境对城市地下空间建设过程中的安全影响,以某在建城市地下“日”形环隧工程为研究对象,基于模糊层次分析法结合专家经验与统计分析法对该工程进行综合风险因素定性与定量分析。将城市环隧建设风险划分为地质环境风险、建筑环境风险、建筑设计风险和施工建设风险四类,并将每种风险细分为两层指标因素。研究表明,该工程建设过程中具有较高风险。根据权重计算结果,建设过程中要着重注意包括临近建筑、地下管网、管线分布等因工程所处复杂建筑环境带来的建筑设计与施工建设风险;两指标层中的风险指标按照权重大小划分为主要、中等、次要影响因素三类,并给出了相应的风险防控对策。研究结果可为未来城市环隧工程建设风险控制与管理提供理论指导。
In order to study the influence of the complex environment on the construction of urban underground space,an underground“日”-shaped urban traffic link tunnel in a city under construction is used as the research object.The risk factors of the project were analyzed qualitatively and quantitatively based on the fuzzy analytic hierarchy process combined with experts experience and statistical analysis.Urban traffic link tunnel construction risks were divided into four categories:geological environment risk,building environment risk,architectural design risk,and construction risk,and each risk was subdivided into two levels of index factors.Studies shows that there are high risks in the construction of this project.According to the results of the weight calculation,it is necessary to pay attention to the building design and construction risks caused by the complex construction environment of the project,including adjacent buildings,underground pipe networks,pipeline distribution during the construction process.The risk indicators in the two indicator layers are divided into three categories:primary,medium,and secondary influencing factors according to their weights,and corresponding risk prevention and control countermeasures are given.The research results can provide theoretical guidance for the risk control and management of urban traffic link tunnel construction in the future.
