摘　　要：随着我国经济社会的高速发展及各种大型建设项目持续落地实施,大型深埋地下隧洞施工项目增多,项目的地质条件复杂多样,时常面临多种极端不利条件地质复合的情况。香炉山隧洞是深埋长大隧洞,地质条件具有“地质博物馆”之称,涌水突泥时常发生,施工中3#支洞上游主洞发生涌水突泥。通过分析涌水突泥段地质、水文条件,对隧洞涌水突泥区采用地表截流及联通试验查找地下水补给源,并结合隧洞涌水突泥段围岩特点,合理设置洞内混凝土堵头,做好排水泄压措施,成功处置了涌水突泥,避免了灾害扩大。With the rapid development of my country’s economy and society and the continuous implementation of various large-scale construction projects,the number of large-scale deep-buried underground tunnel construction projects has increased.The geological conditions of the projects are complex and diverse,and they often face a variety of extremely unfavorable geological conditions.Xianglushan Tunnel is a deep-buried long tunnel with geological conditions,known as the“Geological Museum”.Water and mud burst often occur.During the construction,water and mud burst occurred in the main tunnel upstream of the 3#branch tunnel.By analyzing the geological and hydrological conditions of the water and mud burst section,the surface interception and interconnection test were used to find the groundwater recharge source in the tunnel water and mud burst area.Combined with the surrounding rock characteristics of the tunnel water and mud burst section,the concrete plug in the tunnel was reasonably set,and drainage and pressure relief measures were taken to successfully deal with the water and mud burst and avoid the expansion of the disaster.
