摘　　要：拟建的红岩寺隧道是一座特长公路隧道,构造发育,处于灰岩区,且隧道与暗河基本上处于同一高程,故隧道开挖过程中可能出现突水突泥、塌方等工程事故。在勘察工作中充分分析总结了区域地质及现场地质调查资料、岩溶水文地质调查研究资料、钻孔勘探及试验资料、EH4电磁勘探成果资料及地应力测试资料,形成了工程地质勘察报告。该报告为隧道设计提供了必需的参数;对围护方案提出了建议;对可能突水突泥及塌方的段落做出了预测。Hongyan temple tunnel is a supper long expressway tunnel, which is in the limestone area with complex geological structure developed. The tunnel is at the same elevation with the underground river, so there might be water and mud bursting, and collapse during tunnel excavation. We have analyzed and summarized the regional geology and site investigation data, the karst hydrogeological investigation and research data, the borehole exploration and test data, EH4 electromagnetic prospecting achievement and ground stress test data, and finally prepared the geological survey report. This report provides the necessary parameters for the tunnel design, gives suggestions on the shield schemes and predicts the sections where water and mud bursting and collapse might happen.
