设计潮位过程线新型计算方法在防洪排涝中的应用研究

The New Calculation Method of Design Tide Process is Applied Research in the Flood Protection and Storm Drainage

外江(海)潮水位过程对河口滨海地区的防洪排涝影响较大,在该类规划设计中,需要确定承泄区合适的设计潮位过程。介绍了1种关于设计潮位过程线的计算方法,并在浙江省鳌江下游平原地区排涝规划得到应用。设计表明,该方法简洁高效,计算的设计潮位过程线有较好的实用性,达到预期效果,满足防洪排涝设计的要求。

The tide process influences the flood control and drainage in the tidal river mouth and coastal region,so it is necessary to determine the suitable design tide process of the drainage receiver.There are few studies about the design tide process,and we proposed an experience formula which is suitable for the flood control and drainage.This method has been applied in drainage planning of the Aojiang plains in Zhejiang Province. The result indicates that the method is concise and efficient;the design tide process obtained by this method is practical and achieves the desired effect which meets the requirements of flood control and drainage design.
