| 摘 要： | 改进平湖法是排涝规划中感潮河段水闸水力计算的重要方法。以上海某圩区为背景,针对改进平湖法在实际计算中时间步长的划分问题,研究了不同的时间步长对设计排涝模数的影响,得出在一定的范围内,随着时间步长的增大,排涝模数也增大的结论,并详细分析了产生这些结果的原因。可为利用改进平湖法进行水力计算时选取合理的时间间隔提供依据和参考。

| Abstract: | The improved Pinghu method is an important method for hydraulic computation of sluice in the drainage programming of the tidal reach.This article takes a low-lying region in shanghai as background,aims at the compartmentalization problem of time interval in the actual calculation,studies the impact of different time interval on the designed flood drainage modulus,elicits a conclusion that the designed flood drainage modulus increases along with the increased time interval within a certain scope,and analyses... |
