摘　　要：为解决深切峡谷区特长深埋岩溶隧道因险峻的地形地貌、复杂地质构造等地质条件带来的勘察难题,依托重庆巫溪至陕西镇坪高速公路工程,提出利用“空-天-地”勘察技术手段,从“点-线-面”维度逐步递进,构筑、完善岩溶地质体模型,并对其开展工程地质分析工作。工程实践发现:从空间地质体模型上进行分析,能有效解决隧道线路走廊选择、围岩分级、动态及静态岩溶涌突水、水环境影响等重大地质问题,更好地服务于工程设计,为施工及建设管理提供可靠的地质技术保障。In order to solve the survey problems caused by the steep terrain,complex strata,and geological conditions of deep buried karst tunnels in deep canyon areas,it is proposed to use the"space-air-ground"exploration technology to gradually construct and improve the karst geological body model from the"point line surface"dimension,and carry out engineering geological analysis,relying on the Chongqing Wuxi to Shaanxi Zhenping expressway project.The massive project practice has found that analyzing from the spatial geological body model can effectively solve major geological problems such as tunnel route corridor selection,surrounding rock classification,dynamic and static karst water inrush,water environment impact,etc.,better serve engineering design,and provide reliable geological technical support for construction and construction management.
