摘要:
水库蓄水使库岸边坡稳定性变化较大,以甘肃省九甸峡库区燕子坪(28#)滑坡为例,采用GPS对滑坡的位移进行定期监测,分析蓄水对库岸边坡稳定性的影响规律,并采用边坡熵的方法进行验证.分析结果表明:①蓄水过程可分为3个阶段,包括蓄水位0~70 m,70~100 m和100~130 m 3个阶段,且每个蓄水阶段对滑坡的影响程度不同.②蓄水位100~115 m与115~130 m两个蓄水范围内滑坡的稳定性受影响程度不同.③采用边坡熵的方法验证蓄水与库岸滑坡稳定性的关系是适用的,对于其他类似研究可以提供借鉴作用.
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.
