宜万铁路复杂岩溶隧道施工地质工作方法
|
摘要
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.
The method of geological work for the construction of karst tunnels,and the procedures and contents were put forth. Then,the tunnel management was carried out based on the classification of A,B and C in view of the complexity of karst tunnels concerning the geological and hydro-geological condition,the effect of geological factors on tunnels and the induced environmental problems. Correspondingly,there were three classes for advance geological forecasting with various methods and means. Finally,the disaster evaluation was taken on the basis of geological forecasting. Suggestions on disaster warning and construction countermeasures were put forth for the reference of optimization of design and construction in karst tunnels. This method was successfully applied in on Yi-Wan Railway.
