【摘要】：根據(jù)口岸直水道落成洲守護(hù)工程前后實(shí)測水文資料,分析口岸直水道上淺區(qū)水動(dòng)力條件和分流比的變化情況。結(jié)果表明,落成洲守護(hù)工程實(shí)施后,三益橋淺區(qū)段主流有向河道中心集中的趨勢,有利于主汊內(nèi)深槽的沖刷和航道條件的改善,但右汊內(nèi)流速仍有所增加、分流比進(jìn)一步加大,不利于左汊主航道條件的進(jìn)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 .
