Abstract: By advanced sensor technology, for high steep rock slope behind the powerhouse of Huaguangtan I cascade hydropower station, multi-scale safety monitoring system was built. Considering safety influencing factors, basing on concept of fuzzy mathematics, comprehensive evaluation model was built. The result showed that the influencing degree of different factors with uncertainty on slope safety was fully reflected, and the safety level of the slope was obtained. It was of vital significance for decision making.

Key words: multi-scale monitoring, high-steep slope, fuzzy comprehensive evaluation

摘要： 基于先进的传感器感知技术，针对华光潭梯级水电站一级厂房后边坡岩质高陡边坡这一工程实例，构建了多尺度安全监测系统，并综合考虑边坡安全的各方面影响因素，在模糊数学的思想基础之上建立了高陡边坡的安全性综合评判模型。结果表明，该方法可以全面反映出具有不确定性的各个影响因素对边坡安全性的影响程度，并得到合理的边坡安全性等级，对工程决策具有重要的意义。
