【摘要】 为减少富水区公路隧道施工中的涌水突泥灾害，本文依托古兜山隧道工程，提出了多种针对涌水突泥隧道地段的超前地质预报方法及风险源控制技术：（1）提出了分级管理的隧道超前地质预报方法，根据围岩等级选用地质调查、TSP、地质雷达、超前地质钻孔方法进行综合预报；（2）采用了大管棚、小导管及帷幕注浆超前支护方法，对古兜山隧道涌水突泥风险进行控制，有效避免了在富水区出现涌水突泥现象。更多还原

【Abstract】 In order to reduce the disaster of water inrush and mud inrush during the construction of highway tunnels in water rich areas, this paper, relying on the Gudoushan Tunnel Project, proposes a variety of advanced geological prediction methods and risk source control technologies for water and mud inrush tunnel sections.A tunnel advanced geological prediction method with hierarchical management is proposed, and geological survey, TSP, geological radar and advanced geological drilling methods are selected according to the surrounding rock grade for comprehensive prediction. The large pipe shed, small conduit and curtain grouting advanced support method are adopted to control the risk of water and mud inrush in Gudoushan Tunnel,effectively avoiding the phenomenon of water and mud inrush in water rich areas.更多还原
