| 摘 要： | 大比降排水管水流通常为高速水流,其水力设计已经超过排水设计规范范畴。以实际工程为例,指出该类管道不宜按照有压管路或明渠均匀流计算公式进行水力计算,应按照掺气水流计算,这为实际工程设计提供了参考依据。

| Abstract: | In the sewer pipe with high energy slope, there always occurs the high velocity flow, and its hydraulic calculation is beyond the range of wastewater design specification. The practical project has showed that the hydraulic calculation for sewer pipe with high energy slope shall be done according to the hydraulic formulae for aerated flow, and the hydraulic formulae for pressure pipe or open channel hydraulics can not be used. The conclusion provides the reference for practical engineering design of sewer pipe. |
