摘　　要：北疆某重力坝底孔旁通充水阀因冬季冻裂漏水。在保证安全的前提下,采用封堵球、水下摄像头等设备,在规定的时间段内对其进行了更换,使其在短期内恢复了正常运行。这种特殊处理措施可为类似工程提供有益的借鉴和参考。The bypass water filling valve for the bottom outlet of a gravity dam in the North Xinjiang is leaked due to frost-crack caused in winter. The equipment of ball-sealer, underwater camera, etc. are adopted for replacing the valve in a specified period under the premise of ensuring the safety, and then the normal operation of the valve is recovered in a short period. This special treatment measure can provide a beneficial reference for the similar project concerned.
