| 摘 要： | 岩溶塌陷的产生会严重影响隧道的安全施工及运营,而隧道的开挖又加剧了岩溶塌陷发生的可能性,并使其发生机制变的更加复杂。本文选择隧道埋深、隧道涌水量及距离隧道的远近3个因素来衡量隧道开挖对岩溶塌陷的影响。并以长基岭隧道为例,运用模糊数学理论结合层次分析法,选择了包括隧道埋深、涌水量等在内的14个因素,建立研究区岩溶塌陷模糊综合评判模型,并通过程序与GIS集成实现了研究区岩溶塌陷危险性分区。评价结果对岩溶地区隧道的施工及运营提供依据。

| Abstract: | The emergence of karst collapse severely affects the safety of tunnel construction,where as the tunnel excavation aggravates the occurrence of karst collapse and makes the mechanisms of karst collapse more complicated.Three factors such as the depth of tunnel,the water inflow of tunnel and the distance to the tunnel are selected to discuss the effect of tunnel excavation to karst subsidence.Taking Chang Jiling Tunnel for example,Fuzzy Mathematics Theory and the Analytic Hierarchy process are introduced.Fourteen factors,including the depth of tunnel,water inflow and so on,are selected to establish the fuzzy comprehensive evaluation model.The risk zonation of karst collapse is obtained by combining GIS with programming.Predicting results can be used for the safety of tunnel construction and operation. |
