摘要
岩溶隧道突涌水问题是岩溶地区隧道工程建设中的主要地质灾害之一。基于岩溶隧道突水灾害发生的影响因子，建立了以地层岩性、不良地质、地下水位、地形地貌、岩层产状及层面与层间裂隙等6个地质影响因子为主的评价指标体系；基于加权平均法考虑采用多因素单一综合指标评价方法，建立了隧道突涌水风险评估分析模型，以鸡公岭隧道ZK19＋509～ZK19＋539段为实例，对其突涌水进行风险评估，其评价结果与其他方法所得结果及工程实际情况较为吻合，验证了本方法的合理性与可行性。
Water inrush is one of the major geological hazards during tunnel construction in karst area. Based on the factors of water inrush in karst tunnel, an evaluation system is established which mainly includes geological factors such as formation lithology, unfavorable geology, groundwater level, topography and geomorphology, attitude of rocks, layer and interlayer fissures. Applying the weighted av- erage method and considering the multi-factor single comprehensive index value method, a risk assess- ment model of water inrush in tunnel construction is established to evaluate the hazards of water inrush in karst tunnel. Taking Jigongling Tunnel（ZK19 ＋509 ～ ZK19 ＋539 part） as an example, this paper as- sessed its water inrush in weighted average method and the evaluation result consistent with the actual sit- uation, which verified the rationality and feasibility of this method.
