【摘要】：根据口岸直水道落成洲守护工程前后实测水文资料,分析口岸直水道上浅区水动力条件和分流比的变化情况。结果表明,落成洲守护工程实施后,三益桥浅区段主流有向河道中心集中的趋势,有利于主汊内深槽的冲刷和航道条件的改善,但右汊内流速仍有所增加、分流比进一步加大,不利于左汊主航道条件的进一步改善。
[Abstract]:According to the measured hydrological data before and after the water channel of the port , the change of the hydrodynamic condition and the diversion ratio in the shallow water area at the port of the port is analyzed . The results show that the main flow in the shallow section of the three - benefit bridge has a tendency towards the center of the channel after the implementation of the Lok Ma Chau Conservation Project , which is beneficial to the scouring of the deep trough in the main branch and the improvement of the channel conditions . However , the flow velocity in the right branch is still increased , the split ratio is further increased , which is not conducive to the further improvement of the condition of the main channel of the left branch .
