摘要
水库蓄水后将引起库区岸坡的变形和再造。为了研究其塌岸类型及规模,通过对库区重点岸段的详细地质调查,总结了白龙江某库岸段存在三种主要塌岸模式。并针对不同的塌岸模式和岸坡结构等,预测合理的参数来对各库岸段塌岸规模进行计算,得出极限平衡法更适用于滑移型破坏模式的库岸,佐洛塔廖夫法和类比图解法预测的塌岸结果相接近,卡丘金法整体偏大。
The reservoir after impounding will cause the deformation and en-engineering of the reservoir area. In order to study the bank-collapse deformation, three main bank-collapse modes of a reservoir in Ballong River are summed up here through geological investigations. At the same time, the different methods and reasonable parameters are adopted to pre- dict and calculate the bank-collapse scale in view of different bank-collapse modes and bank structures. Then, it is ob- tained that the limit equilibrium method would be more suitable for method and analogously graphic method are close, and the results of the bank of sliding type, the results of Zolotalove Kachujin method are almost bigger overall.
