| 摘 要： | 一河多桥桥孔长度计算与一河一桥的主要区别在于对总流量进行重分配,然后再简化为单桥的孔径计算,根据每座桥的桥前壅水高度,采用壅水平衡法综合确定每座桥的孔径长度,从而确定一河多桥的总长度。

| Abstract: | The major difference between the calculations of several bridges over a section of the river and a single bridge over it is to redistribute the total flow,then to simplify the calculation as the span of a single bridge.According to the dammed water height in front of every bridge,the dammed water balance method is adopted to comprehensively determine the span length of every bridge,so as to figure out the total length of a multi-bridge over one river. |
