摘要
为分析峡江水利枢纽右岸边坡的加固效应,评价该边坡的稳定性,利用基于离散元的强度折减法,选取不同的边坡范围分别建立数值模型,分析了削坡减荷和预应力锚索加固处理后的边坡稳定性。结果表明:对峡江右岸边坡的削坡减荷处理和预应力锚索加固处理是有效的,削坡减荷对减小边坡变形有明显效果,预应力锚索加固使边坡安全系数较明显提高。研究成果可为类似工程处理提供借鉴。
In this paper,the reinforcement effect and the stability of the right slope of the Xiajiang River are ana⁃lyzed with the different models built by DEM-based Strength Reduction Method for different sideslope scopes.The deformation under different conditions are studied,including the natural slope cut and the slope reinforce with the cables.It is showed that the slope cut and the reinforcement with the cables worked.The deformation of the slope de⁃creased obviously after the slope cut for reducing load and prestressed cable reinforcement.This research result can provide a reference for similar projects.
