| 摘 要： | 在覆盖层上建坝,覆盖层材料性质对坝体沉降变形影响较大.为减小坝体沉降,需要对覆盖层进行开挖回填.本文以丹巴水电站为例,拟定覆盖层处理时回填级配料、、回填级配料并固结灌浆等4种方案,根据室内试验参数,分别进行三维有限元计算分析,并对比分析计算结果,为开挖回填方案选择提供参考性意见.

| Abstract: | Overburden materials have great influence on the settlement of the dam. In order to reduce dam settlement,the materials of overburden need to be replaced. Based on the case study of Danba Reservoir,four solutions are discussed in the essay,mainly as burdening backfilling and consolidation grouting. Material parameters of indoor test results are inspected and analyzed by finite element calculation,on the basis of the simulation of different excavation and backfilling scheme,providing reference for the design and selection of a dam project. |
