双曲拱坝施工稳定性控制研究

Study on Construction Stability Control of Double Curvature Arch Dam

双曲拱坝是一种可靠安全、经济合理的坝型,在设计时,坝肩的稳定性是坝体设计和施工时需要重点考虑的问题。本文以八峰水库工程为例,通过构建三维地质模型,模拟了双曲拱坝开挖和浇筑过程中的稳定性,然后根据模拟结果分析了坝肩岩体浇筑和开挖过程中应力变形情况,保证了双曲拱坝施工的稳定性,可为类似工程提供借鉴。

Double Curvature arch dam is a reliable,safe,economical and rational dam type. In design,the stability of the dam abutment is the key considered during dam design and construction. In the paper,Bafeng Reservoir Project is adopted as an example. The stability in double curvature arch dam excavation and pouring is simulated. Then,the stress deformation condition in dam abutment rock pouring and excavation is analyzed according to the simulation results,thereby ensuring the stability of double curvature arch dam construction,and providing reference for similar projects.
