| 摘 要： | 在已有研究的基础上,定量分析了津槽分流与水深比、糙率比、河宽比的相互关系,并根据分析结果,综合考虑影响滩槽流量的主要因素和滩槽间的交互作用,构造了概化断面的潍槽流量比的计算结构式.最后采用滩、槽分流比的实测资料对该式进行验证.结果表明,该公式计算的滩槽分流比与实测值较为接近,可供相关工作者参考.

| Abstract: | Based on previous researches,the relationship between discharge diversion ratio of compound channel flows and the influencing factors including water depth,river roughness and channel width are quantitatively analyzed through the shallow water hydrodynamic model.Taking the influencing factors and the interaction between floodplains and the main channel into account,the article proposes a new calculation method of discharge diversion ratio in compound channel.In the end,the formula is verified by experimenta... |
