云南鲁甸红石岩堰塞湖右岸620 m高边坡综合监测技术

Comprehensive monitoring technologies for the 620 m high slope on the right bank of Hongshiyan barrier lake in Ludian County of Yunnan

云南8·3鲁甸地震形成的堰塞湖总库容2.6×10^(8)m^(3),属大型堰塞湖,危险级别为极高,堰塞体溃决损失严重,风险等级为I级。笔者介绍了鲁甸地震形成的红石岩堰塞湖右岸620 m高边坡的工程地质情况,分析了影响高边坡稳定的诸多因素,并针对各因素提出了适用于高边坡的综合监测技术。

The total storage capacity of the barrier lake formed by the 8·3 Ludian earthquake in Yunnan is 2.6×10^(8)m^(3).As a large barrier lake,its risk level is extremely high.The loss caused by landslide dam burst is serious,with a risk level of I.This paper introduces the geological conditions of the 620 m high slope on the right bank of Hongshiyan barrier lake,analyzes various factors affecting the stability of the high slope,and proposes a comprehensive monitoring system suitable for the high slope.
