| 摘 要： | 钢纤维混凝土是控制钢衬钢筋混凝土裂缝的一个有效途径，但钢纤维加入到混凝土中使结构计算变得复杂，现有的钢衬钢筋混凝土压力管道的计算方法不再适用，因此根据结构的受力特点以及钢纤维混凝土的特性提出了钢衬钢混凝土压力管道的计算方法，该方法是受力全过程分析；并着重进行了混凝土裂后的非线性计算。

| Abstract: | In comparison with conventional reinforcement, steel fiber reinforcement is more efficient for crack control of concrete penstocks with steel lining. However, the unique post\|peak behaviors of SFRC on tension make the design and analysis of penstocks more complicated than ordinary reinforced concrete, that is, the present calculation methods of penstocks can not actually describe the structural stress status. So in this paper a simple and valid method of stress analysis for steel fiber concrete penstocks under the internal water pressure is developed, especially non\|linear analysis after cracking is carried out in detail. |
