针对黄金坪水电站阻抗长廊式调压室空间结构受力条件复杂的问题,采用FLAC3D软件对调压室结构及其外部围岩进行了数值模拟,分析了不同工况下调压室衬砌结构的受力状况,并依据三维数值分析结果对调压室衬砌结构进行了配筋设计。结果表明,该调压室结构配筋设计应将最高涌浪水位工况作为控制工况,阻抗板为调压室衬砌受力最大的部位,为结构配筋的重点。
In view of the complicated stress conditions of the space structure of impedance corridor in Huangjinping Hydropower Station, the structure of the surge chamber and its external surrounding rock are simulated by FLAC3D software. The influence of different conditions on the lining structure of the surge chamber is analyzed Stress conditions, and according to the results of three-dimensional numerical analysis of the pressure chamber lining structure reinforcement design. The results show that the structure design of the surge chamber should be the highest surge water level conditions as a control condition, the impedance plate for the pressure chamber lining the largest force of the site, the focus of the structural reinforcement.
