雨水道设计中的节约,主要是暴雨强度公式与径流系数及满溢周期的问题。这些过大或过小,都将会造成浪费和物质损失。此外,有些看来似乎是不大重要的问题,但其经济意义也是不容勿视的。兹提出以下问题加以讨论。一压力流的问题压力流的理论,已为苏联学者基本解决,但并未完全解决。由于雨水道设计的近似性,对实际应用就没有多大的影响,苏联已有了广泛的应用,在我国也有了介
The savings in the design of storm waterways are mainly the rainstorm intensity formula and the runoff coefficient and the overflow period. Anything too large or too small will cause waste and material damage. In addition, some seem to be less important issues, but their economic significance can not be ignored. I hereby raise the following questions for discussion. The theory of pressure flow in a pressure flow has been basically solved by Soviet scholars, but it has not been completely resolved. Due to the similarity of the design of the stormwater channel, there is no significant impact on practical applications. The Soviet Union has already had a wide range of applications and has also been introduced in China.
