摘要

摘要: 结合龙背湾水电站混凝土面板堆石坝工程施工实际情况,采用三维有限元分析方法模拟面板坝施工过程中挤压边墙的变形发展过程,分析研究面板堆石坝施工期坝体变形规律和受坝体变形而导致挤压边墙变形的发展规律。依据监测资料,对施工期挤压边墙变形进行了系统分析,并通过对比大坝三维仿真分析计算结果及实测数据,验证了对大坝进行三维仿真分析的合理性。根据大坝三维计算的结果对大坝填筑方案进行了优化,计算结果表明优化坝体填筑顺序后,施工期挤压边墙的变形有明显减小。

Abstract: Combining the actual construction situation of Longbeiwan hydropower station concrete face rockfill dam project, the three-dimensional finite element analysis method is used to simulate the deformation development process of extruded sidewall during the construction process of concrete face rockfill dam. The dam deformation rules and development rules of extruded sidewall due to dam deformation are investigated. According to the monitoring data, deformations of the dam body and extruded sidewall are analyzed. By comparing the calculated results of three-dimensional simulation with the measured data. The reasonableness of three-dimensional simulation analysis for the dam is verified. The filling program for the dam is adjusted according to the calculated results. The deformation of extruded sidewall during construction is significantly reduced after the filling order for the dam is adjusted.
