| 中文摘要: |
| 根据黄河下游堤防堤顶区域的产汇流特性，将堤顶产汇流区概化为平行四边形区域，运用坡面水流运动波描述方法，计算了产汇流时间，提出了堤防排水沟设计洪峰流量计算公式、排水沟断面设计及间距的优化方法;并给出了实际例证。优化结果表明，黄河下游堤防排水沟间距为100m左右;排水沟断面为矩形时，宽取0.5m、深取0.4m；断面为梯形且边坡系数为2时，宽取0.4m、深取0.4m是比较合适的。 |
| 英文摘要: |
| According to the characteristics of dike top, the runoff producing area on the top of dike is simplified as a parallelogram. The method for describing the flow on slope is applied to calculate the runoff generating time and the formula for calculating the peak flood discharge of drain ditches is proposed. The optimal designed cross section of ditches and ditches interval is suggested. It is concluded that the best interval of ditches is 100m, the width and height of rectangular drain ditches is 0.5m and 0.4m respectively, and the bottom width of trapez oid drain ditches is 0.4m with 1:2 slope on both side. |
