三峡水电站钢衬钢筋混凝土压力引水管混凝土裂缝计算研究

Study on the crack computation of the steel lining reinforced concrete penstock in Three Gorges Hydropower Station

采用较符合钢衬钢筋混凝土压力管道实际工作状态"内蜕壳法"进行限裂校核计算,并在研究过程中对"内蜕壳法"的三点不足之处进行了改进,使计算值与三峡水电站压力引水管1∶2大比尺结构模型试验值相当吻合,具有很好的效果.

In this paper the author checkout the arithmetic of restrict crack by the method of 'nei-tui-qiao'that is suit to the practical running estate of the steel lining reinforced concrete penstock in Three Gorge Hydropower Station.The author ameliorates three defects in the way of 'nei-tui-qiao'and makes the result accord with result of physical model experiment (scale 1∶2).The result of measures is fine.
