摘　　要：广邻快速公路为连接广安市与邻水县的重要高等级公路,其控制性工程华蓥山特长隧道工程地质条件和水文地质条件极其复杂,施工及运营风险极高。为了降低隧道工程施工及运营风险,分析了隧址区的工程地质条件,重点论证了岩溶及岩溶水与煤矿采空区2类重大工程地质问题,并通过对比不同方案的地质条件,确定了岩溶发育路段短、岩溶水危害较小、对环境影响较小、煤矿采空区长度短的隧道方案。Guang′an-Linshui Highway is an important high-grade road connecting Guang′an City and Linshui County.The engineering geological conditions and hydrogeological conditions of Huayingshan Tunnel,the dominant engineering,are extremely complex,and the construction and operation risks are extremely high.To reduces the construction and operation risks of tunnel engineering,this paper analyze the engineering geological conditions of the tunnel site area,with a focus on two major engineering geological issues:karst and karst water,and coal mine goaf.According to comparison of geological conditions under different schemes,the tunnel scheme with short karst development section,small karst water hazard,small impact on the environment,and short length of coal mine goaf is determined.
