摘要 以宜万铁路岩溶隧道的施工地质技术实践为例,介绍了施工地质作为工程勘察阶段工程地质勘探在施工阶段的延续,用以在施工过程中解决勘察阶段所没有或不能解决的工程地质问题。施工地质以超前地质预测预报为主体,以规避大型施工地质灾害为目的,在施工阶段针对可能发生的隧道围岩变更;可能存在的溶腔、断层构造、地下暗河的预测预报;可能引发的水文环境地质问题;工程竣工以后可能存在的隐伏地质病害等,在隧道施工环境条件下为保证施工进度、保证施工安全、保证工程效益、保证工程质量所进行的综合工程地质工作。施工地质包括综合超前地质预报、水文观测和隧道周边及隧底隐伏岩溶探查。 Taking the construction geology technology practice of karst tunnels on Yichang-Wuanzhou Railway as an example, construction geology, which is a continuation of engineering geological exploration in construction stage, can be used to solve the problems which do not exist or cannot be solved in exploration stage. Taking advanced geology predication as its subject, aiming at avoiding large-scale construction geological harzards, construetion geology refers to the comprehensive engineering geology work for ensuring construction progress, construction safety, engineering benefit and project quality, such as predicting possible displacement of tunnel surrounding rock; forecasting potential salt cavities, faults and underground rivers; finding out potential hydrogeology problems and concealed geological disasters after project completion, etc. Construction geology includes comprehensive advanced geology predication, hydrogeological observation and concealed karst exploration.
