| 摘 要： | 圩区常受洪涝的双重威胁。圩区设计排涝流量计算,对圩区的水安全,有效减免涝灾经济损失有着重要意义。以水文学方法,以设计流量过程调蓄计算方法确定设计排涝流量,并以朱家角镇圩区为研究对象,分析了圩区设计排涝流量与水面率关系,得出设计排涝流量与水面率之间的非线性关系,可采用抛物线方程进行拟合,设计排涝流量与水面率关系的参数与圩区面积有很好的响应关系。

| Abstract: | Polder areas are threatened by flood and waterlog frequently. Calculating design drainage discharge have important significance for water safety and derating economic losses of waterlog in the polder areas. In this paper, authors calculated design drainage discharge by routing design discharge hydrograph in the Zhu Jia Jiao Town, analysed the relations of design drainage discharge and water surface ratio, educed nonlinear both relations. The relations can be matched by parabola equations, and the parameters of both relations are good on area of polders. |
