摘要
结合湘江下游2 000吨级航道建设,分析现有跨河桥梁对航道等级提升的影响,提出对通航净空不够的桥梁,应根据现状船型分析碍航天数,并综合考虑桥梁改造难度确定处理方案,既保证通航安全,又兼顾航道升级的经济可行性,不能机械执行《内河通航标准》。
The effect of river-crossing bridge on waterway upgrading is analyzed based on the construction of Xiangjiang river 2000 t downstream channel and a concept is proposed that for those bridges with insufficient clearance, treatment scheme which guarantees the navigation safety and also takes the economic feasibility of waterway upgrading into consideration, shall be determined by considering the days of navigation obstruction analyzed based on the existing ship-type and the difficulty of bridge reconstruction.
