一、引言以2004年9月23日黄河上游的公们峡水电站首台30万kW机投产发电为标志,我国水电装机容量突破1亿kW大关,水电站堤坝总数达到9万座,水电开发程度达到32％,我国水电开发的历史也迈上了崭新的台阶。然而,由于水文、地质、施工质量及老化等多种原因,部分水电站大坝存在安全隐患,必须对大坝原型进行监测。经过多年积累,监测数据已经达到相当的规模,在此基础上开展的监测数据挖掘探索,为大坝安全监控理论的研究及应用提供了新的思路和可能的途径。
I. INTRODUCTION Taking the first 300kW machine put into operation at Gongzixia Hydropower Station on the upper reaches of the Yellow River on September 23, 2004 as a symbol, China’s installed capacity of hydropower exceeded 100 million kW, the total number of hydropower stations reached 90,000, and the hydropower development level At 32%, the history of China’s hydropower development has also taken a brand new stage. However, due to various reasons such as hydrology, geology, construction quality and aging, some dam dams have potential safety hazards and the dams prototypes must be monitored. After years of accumulation, the monitoring data has reached a considerable scale. Based on this, exploration of monitoring data mining has provided new ideas and possible ways for the research and application of dam safety monitoring theory.
