| 摘 要： | 龙滩水电站进水口边坡最大坡高达420m，岩质高边坡稳定问题是设计必须解决的重大技术问题之一，通过多种数值分析方法确定了合理的开挖体型，恰当的加固支护措施以及施工程序，并对多种运行工况进行了模拟。介绍三维有限元稳定分析计算结果，计算表明：边坡在施工期整体稳定，大坝建成后有利于边坡稳定；拟定的边坡加固支护措施及预应力锚索的加固作用明显，设计参数是可行的。

| Abstract: | s: As the max.height of the intake side slope of Longtan hydropower station is as high as 420 m,slope stability is one of the key technical problems in design.Various kinds of mumerical analysis mehtods are adopted to define a rational excavation outline and proper strengthening measures,as well as the construction process.Operations under different conditions are also simulated.The results of 3D FEM analysis show that the side will be stable during the dam construction and more stable after the dam is constructed;The strengthening roles of proposed strengthening measures and pre stressed anchor cable are obvious,proving the feasibility of the design data. |
