Abstract

Abstract:

By analysis of the process lines of crack opening and the displacement of dangerous rock mass on the top of the high slope on the right bank of Hongshiyan barrier lake in Ludian County of Yannan, the result shows that the slope is unstable since monitoring began. The successful prediction and warning of the large-scale slope collapse provides a useful reference for monitoring similar high slope

formed after earthquakes.

Key words:

barrier lake, earthquake, high slope, collapse warning

摘要：

分析云南鲁甸红石岩堰塞湖高边坡坡顶裂缝张开过程线及坡面危岩体位移变化过程线可知，自监测以来，边坡就处于不稳定状态。对该边坡大面积滑塌进行了成功预警，可为今后国内外类似地震高边坡的监测提供参考。
