| 摘 要： | 从计算具有混凝土径向裂缝的管道结构位移出发，导出了计算钢衬钢筋混凝土压力管道混凝土裂缝宽度的半解析，半经验的实用数学模型，经与１：１比尺真实材料结构模型试验结果相对照，计算值与试验符合良好，文中还给出了算例并讨论了控制裂缝宽度的途径。

| Abstract: | On the basis of the structural displacement calculation of concrete penstock with radial cracks, the practical mathematic model for calculating concrete crack width in steel--lined reinforcement concrete penstock has been gained. Compared with the test results of real material structural model with the scale of 1: l,the calculation value is nearly accord with the test result. This paper also presents the calculation example and discusses the ways to control the crack width. |
