| 摘 要： | 通过对实测资料的分析,证明单宽流量分布曲线除两岸边向下凹、岸边流量系数为0.42以外,其余在部分宽内总体情况是呈直线变化的.据此,提出了用单宽流量直线变化代替水深与流速直线变化计算流量的方法,并用实例对不同垂线、不同方法的精度进行了比较,证明单宽流量法不但克服了流量国标法存在的问题,提高了流量精度,而且简单方便,实用有效,可作为修订流量国标的重要依据.

| Abstract: | An analysis of the surveyed data shows that the general distribution of single width runoff is in linear change, except that it is concave on both sides and the bank runoff coefficient is 0.42. Therefore, the proposal of calculating runoff by using linear change of single width runoff instead of that of the velocity of flow is made and a comparison of the precision of different vertical lines and different methods with practical examples proves that single width runoff method not only solves the problems existing in the runoff state standard method and improves the runoff precision, but is also simple and efficient. It provides an important gist for the recession of the runoff state standard. |
