混凝土坝下游面钢衬钢筋混凝土压力管道是近年来在国内外发展起来的新型结构。本文提出了这种管道在内水压力作用下应力计算和强度分析的方法,已为我国某一大型水电站设计应用。其中简化为轴对称结构的计算方法,与国外的方法比较,简便得多,且可得相同的精度。 The steel lined reinforced concrete penstocks on the downstream face of concrete dams are new structures developed at home and abroad in recent years. This paper proposes the method of stress calculation and strength analysis of this kind of pipeline under internal water pressure, which has been applied to a large-scale hydropower station in China. Among them, the calculation method for the axisymmetric structure is simplified, and it is much simpler and more accurate than the foreign methods, and the same accuracy can be obtained.
