通过研究岩溶隧道施工地质工作方法,给出了岩溶隧道施工地质工作的程序和内容:根据各隧道的工程地质和水文地质条件、地质因素对隧道施工影响程度及诱发环境问题的程度等,将岩溶隧道复杂程度分为A级、B级、C级进行管理;针对不同复杂程度的分级、不同类型的地质问题,将超前预报工作分为A级、B级、C级3个等级,并选择不同的预报方法和手段进行预报;最后根据预报结果,进行灾害评估,提出灾害预警和工程措施的建议意见,供岩溶隧道优化设计和施工参考.该方法体系在宜万铁路得到了成功应用.
By studying the geological working methods of karst tunnel construction, the program and content of karst tunnel construction geological work are given: According to the engineering geological and hydrogeological conditions of each tunnel, the influence degree of geological factors on tunnel construction and the degree of environmental problems induced, The tunnel complexity is divided into A level, B level and C level for management. According to different levels of complexity and different types of geological problems, the advanced forecasting work is divided into three levels: A level, B level and C level, Finally, according to the forecast result, the dissertation carries out the disaster assessment and puts forward the suggestion of disaster early warning and engineering measures for the optimization design and construction reference of karst tunnel.The method system has been successfully applied in Yichang-Wanzhou Railway.
