摘要
隧道涌突水是常见的施工灾害之一,严重威胁施工及人员设备安全。如何评价施工中涌突水存在的风险,以及涌突水量的预测对隧道施工建设具有重大意义。依托米仓山隧道工程项目为实例,通过全面的地质调查和地质跟踪,根据岩溶隧道涌水专家评判系统,预测评估可能发生涌突水的类型,进一步筛选评价指标,采用模糊层次分析法fuzzy analytic hierarchy process(FAHP)预测涌突水危险度,最后选取适宜理论公式,定量计算涌水量。该研究对高风险岩溶隧道涌突水预测研究思路与研究方法具有一定的指导意义。
Water burst when tunneling is one of the frequent construction disasters,it is a serious threat to the construction safety of equipment and personnel. How to evaluate water outrush risk in the construction process and predict water inrush rate in tunneling is of great significance. In the engineering program of Micangshan tunnel,comprehensive geological survey and geological tracking are invited. By using the expert judgment system in karst tunnel gushing water, predicting possible flood water gushing type is achieved. After selecting evaluation indexes,the fuzzy analytic hierarchy process is invited to predict flood water gushing risk. Finally, suitable theoretical formulas are used to calculate the volume of water inflow. The study has a certain guiding significance to the research ideas and research methods on high-risk karst tunnel gushing water gushing prediction.
