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
