摘要
隧道岩溶问题是当前国内外隧道施工中的重大难题,岩溶工程地质问题对地下工程建设和运营管理造成很大的影响。洞湾隧道施工过程中发现隧道底板以下发育大型溶洞,通过配合测量断面同时进行地质水文地质调绘、物探结合钻孔详细查明溶洞规模、形态、大小、埋深及与线路的关系,查明隧道底板以下岩溶发育情况以及与隧道顶板的距离,评价隧道围岩的稳定性,并提出岩溶施工处理措施建议,为隧道施工及岩溶整治设计提供地质依据。
Karst problem is a major problem in the current domestic and international tunnel construction, a lot of impact on karst engineering geological problems of underground construction and operations management. Tunnel construction process, the following development of a large cave in the tunnel backplane holes Bay geological hydrogeological tone painted simultaneously with the measurement section, borehole geophysical combination of detail to identify the scale of the cave, the shape, size, depth, and the relationship with the line, to identify the distance of the metro plate karst tunnel roof, the evaluation of tunnel surrounding rock stability, and put forward the proposal of the karst construction measures, to provide the geological basis for the tunnel construction and karst remediation design.
