摘　　要：随着我国西部大开发战略向纵深推进,西南地区大规模开展基础设施建设。西南地区地质条件复杂,在隧洞、电站地下厂房、跨流域引调水等地下工程中多遇到软岩大变形、塌方、岩爆、涌水突泥等地质灾害,其中尤以涌水突泥灾害最为严重。以滇中引水工程深埋长隧洞香炉山隧洞2^(#)下游段工程实践为背景,对穿越富水活动断裂带的地质背景、开挖过程中揭露地质条件进行分析,及时研判施工安全风险,并提出处置措施建议,为隧洞安全、顺利穿越富水活动断裂带提供了基础依据,也为类似深埋长隧洞穿越富水断裂带提供一定的借鉴意义。With the deepening of China's western development strategy,large-scale infrastructure construction is being carried out in the southwest region.The geological conditions in the southwestern region are complex,and geological disasters such as soft rock deformation,collapse,rock burst,and water and mud inrush are often encountered in underground projects such as tunnels,underground power plants,and cross basin water diversion.Among them,water and mud inrush disasters are the most serious.This article takes the engineering practice of the downstream section of Xianglushan Tunnel 2^(#) in the deep buried long tunnel of the Central Yunnan Water Diversion Project as the background,analyzes the geological background of crossing the rich water active fault zone and the geological conditions exposed during excavation,timely assesses construction safety risks,and proposes disposal measures and suggestions.This provides a basic basis for the safe and smooth crossing of the rich water active fault zone of the tunnel,and also provides certain reference significance for similar deep buried long tunnels crossing the rich water active fault zone.
