摘　　要：天桥水电站位于黄河干流上少有的高水头岩溶承压水区,而岩溶承压水的存在是影响泄洪闸闸基稳定的重要因素之一.结合电站蓄水后对工程区岩溶承压水水位观测记录及处理经验,分析了其分布规律、渗透运移特征及对电站闸基稳定的影响,提出了对新增泄洪闸闸基承压水处理的措施及建议.Tianqiao Hydropower Station is located in the area with high water head and karst confined water in the main stream of Yellow River. Karst confined water is one of main influencing factors upon the stability of release sluice foundation. Based on the water level observation records of karst confined water in the project area after water storage as well as the treatment experience, the distribution law, the permeability characteristics of karst confined water, and its influences on the stability of release sluice foundation are ana lyzed. The treatment measures for confined water of new release sluice foundation are proposed.
