地铁隧道施工过程中均会出现不同程度的渗漏水问题,而这些渗漏水问题不仅影响施工,还会影响地铁以后的运营。因此,建立了以外界环境影响、施工质量、防排水体系、机械设备与组织管理为1级指标以及19个2级指标的地铁盾构法的施工阶段渗漏水评价体系,利用熵信息计算各指标的权重,建立基于模糊熵的风险评价模型。并以某地铁为例,验证该评价模型。这些研究能有效的预防和减少地铁隧道渗漏水风险的发生,为以后类似工程提供理论依据。
Subway tunnel construction process will be different levels of seepage water problems, and these seepage problems not only affect the construction, but also affect the operation of the subway after. Therefore, the evaluation system of seepage water in construction stage of metro shield method with external environmental impact, construction quality, drainage system, mechanical equipment and organization management as 1 level indicator and 19 2-level indicators was established. Using entropy information to calculate Index weight, establish a risk assessment model based on fuzzy entropy. Taking a subway as an example, this model is validated. These studies can effectively prevent and reduce the risk of subway tunnel seepage water and provide a theoretical basis for similar projects in the future.
