| 摘 要： | 单宽流量法基本假设是：全断面各部分宽内的单宽流量呈直线变化。为了证明该假设的正确性并探求天然河道中的流量校正系数值β〖TX－〗q与岸边流量系数αq以及其变化情况，收集了长江干支流共16个站的流量Ⅲ型误差试验资料317次，对公式中的β〖TX-〗q值与αq值进行了验证。计算和拟合的结果证明，断面流量校正系数在天然河道中接近于１，即该假设正确。同时，介绍了流量校正系数值β〖TX－〗q与岸边流量系数αq值的计算方法和步骤，有助于单宽流量法的推广应用。

| Abstract: | The basic hypothesis for unit width discharge method is that the unit width discharge in any partial width of the whole cross section changes linearly.In order to verify the hypothesis and explore the variation of discharge correction coefficient and bank side discharge coefficient in natural channels,we collected error test data of type III discharge in 16 stations with 317 measuring times in the mainstream and tributaries of Yangtze River.The discharge correction coefficient and bank side discharge coeffi... |
