Application and Analysis of Inference Formulas in Rainwater Pipe and Canal Design:Taking the Neitianxi Road(Fangyang East Third Road to Xiang'an North Road Section)Project in the Xiang'an Area of Tongxiang High-tech New City as an Example

工程设计中,雨水设计流量通常采用推理公式进行计算,本文简要阐述了推理公式的假设条件和计算思路,对其所涉及的各个参数进行分析,并结合工程案例对比面积叠加法和流量叠加法的不同。结果表明,各个参数对推理公式计算结果影响很大,工程设计中应根据实际情况进行取值;在相同设计条件下,流量叠加法计算雨水设计流量大于面积叠加法计算流量。

In engineering design,the design flow rate of rainwater is usually calculated using inference formulas.This article briefly explains the assumptions and calculation ideas of inference formulas,analyzes the various parameters involved,and compares the differences between area superposition method and flow superposition method with engineering cases.The results indicate that each parameter has a significant impact on the calculation results of the inference formula,and values should be determined according to the actual situation in engineering design.Under the same design conditions,the calculation of rainwater design flow using the flow superposition method is greater than the calculation of flow using the area superposition method.
