摘　　要：富水区修建深埋长隧洞必然会破坏原有地下水系的平衡,进而对施工和周边水文地质环境产生不利影响。隧洞群开挖过程中,地下水的运移、影响及隧洞涌水量等研究是一个受多种因素影响的复杂的三维问题,依托锦屏二级水电站引水隧洞群工程,研究隧洞施工过程中山体内部地下水的运移情况,将目前进度下的分析结果和实际监测到的结果进行对比,验证了分析方法和结果的可靠性,在此基础上预测隧洞群贯通后地下水的分布状态,并分析其对工程区内的两大泉(磨房沟和老庄子泉)及当地居民生活用水的影响,进而研究并提出锦屏隧洞施工涌水的控制措施和控制标准,为设计、施工提供参考依据。It is inevitable that the building of long deep-buffed tunnels in water-enriched area will destroy the original balance of groundwater, which will have negative effects on construction and hydrogeological environment nearby. Water transport in mountain and its influence as well as water inflow into tunnels during excavation are complex three-dimensional（3D） problems influenced by a number of factors. Taking Jinping II hydropower station for example, the transport of groundwater in mountain rock during construction period has been studied. A comparison between the calculated results and the observed data under present circumstances indicates that the method and results are satisfactory, and then the distribution of groundwater after excavation is studied as well as its influence on the two springs（Mofanggou and Laozhangzi springs） nearby and domestic water of local people in construction area. Furthermore, control measures and criteria of water inflow in tunnels are proposed for design and construction.
