摘要
目前,长江上已建桥梁越来越多,尤其主城区及发达区域建设的密度更大,导致桥梁建设与码头等临河建筑物安全间距及需求的矛盾越来越突出。在确保航道畅通与通航安全的前提下,为合理利用岸线资源,进行桥梁与码头等临河建筑物间距研究十分必要。以GB 50139—2004《内河通航标准》为指导,科学分析桥梁与码头等临河建筑物之间的相关关系,提出桥梁与码头、锚地、船台、取水口等临河建筑物间距的控制原则及确定方法。此外,讨论河道中相邻过河建筑物紧邻布置的情况下桥梁数量控制与通航孔布置要求,以求减小对通航的不利影响,更好地为内河航运事业及沿江经济建设发展服务。
At present, more and more bridges are built on the Yangtze River, thus the building density is large in main urban areas and developed regions, which leads to the phenomenon that the spacing between the new bridge and old riverside buildings such as port is insufficient. On the basis of GB 50139--2004 Navigation standard of inland waterway, we analyze the method of the researeh about spacing between bridge and riverside buildings such as port, anehorage ground, slipway and water-intake. Furthermore, the requirement about the bridge number eontrol and the navigation opening arrangement are discussed to reduee the impact on navigation and better serve the inland navigation industry and eeonomie construetion along the Yangtze River.
