| 摘 要： | 通过总结已建桥梁对通航的影响,对跨河桥梁建设的现状进行了分析,提出了影响桥区安全通航的主要因素。其中最重要的是水流情况,其次是风、水深和航道宽度及通航孔净宽。将研究结论应用于松陶铁路第二松花江特大桥的通航论证工作中,对该桥的结构、航线选择进行了论证优化,为桥梁建设提供了合理建议。

| Abstract: | Based on the influence of constructed bridges on navigation,the present construction situation of crossing bridge was analyzed.Then main factors effecting the navigation safety in bridge area were proposed.One of the most important influencing factors was water-flow condition,the second were wind,water depth,channel width and width of navigable bridge opening.The obtained conclusions were applied in the Second Songhua River Bridge′s navigation demonstration of Songtao railroad.The bridge structure and the route choice were analyzed and optimized.The results can provide reasonable suggestion for the bridge construction. |
