摘要
对某巨型水电站坝后钢衬钢筋混凝土管道几种截面选型方案进行了探讨。利用空间正交各向异性块体夹膜单元及非线性有限元分析,对钢衬钢筋混凝土管道垫层包角及弹模进行了详细研究,提出了钢衬与外包钢筋混凝土联合作用管道的方案。
The research about several steel liner reinforeed concrete penstock sections of a gigantic hydrolic project is conducted here. The encasing area and elastic modulus of the spacer is stuided attentively by using the space orthotropic brick element with membrance and NFEM analysis. The cooperating penstock model of steel liner and reinforced concrete is presented.
