Abstract: In a complex geological conditions, Longyangxia hydropower station has a high dam and a large reservoir, the stability of Hushan slope is important to engineering safety. In view of the importance of Hushan slope and its problems in operation over the years, a series of engineering treatment measures have been taken. In order to monitor the safety and operation of Hushan slope, an integral monitoring system has been installed, and the monitoring in daily and special periods such as flood discharge has been strengthened. Therefore, reliable, accurate and effective monitoring data have been accumulated, laying a foundation for the analysis and evaluation of safety and operation of Hushan slope. Based on the comprehensive analysis of monitoring data and in combination with the engineering treatment measures, the actual operation state and stability of Hushan slope are evaluated.

Key words: Longyangxia hydropower station, Hushan slope, safety monitoring, operation evaluation

摘要： 龙羊峡水电站坝高、库大、地质条件复杂，下游虎山坡的稳定对整个枢纽工程安全具有重要的意义。鉴于 虎山坡的重要性和多年来运行中出现的问题，采取了一系列工程措施进行综合处理。另外，为监控虎山坡的安全 运行状况，布设了一套完整的监测系统，并加强了日常及泄洪等特殊时期的监测，积累了可靠、准确、有效的监测 资料，为虎山坡安全运行性态分析评价奠定了基础。通过对虎山坡多年监测资料进行综合分析，并结合工程处理 措施，评价其实际运行状态和稳定性。
