- Abstract:
-
The landslide stability is affected by the reservoir impoundment in a large degree, taking an exam-ple of Yanziping(28#)Landslide of Jiudianxia reservoir in Gansu province. The landslide displacement was monitored by using GPS regularly for analyzing the law of the landslide stability affected by the the impound-ment, and the law is validated by using the method of slope entropy. The results show that:(1) the process of impoundment can be divided into three stages including the 0~1/2 , 1/2 to 3/4 and 3/4 above the stage of the storage level,which is affected to different influence degrees;(2) the landslide stability is affected at dif-ferent levels between the range of water levelⅠ(100 m~115 m) andⅡ(115 m~130 m) in different degree;(3) it is suitable that the relationship between impoundment and the stability of reservoir bank landslide is val-idated by using the method of slope entropy with being provided by other similar studies.
