摘要
乐山港一期工程位于岷江老木孔航电枢纽库区右岸,地处老江坝江心洲右汊出口附近。受分汊出口水流的影响,拟建港区存在斜流与回流,对船舶进港、出港、停泊、装卸作业及港池水深维护等有一定的影响。为弄清洲尾的通航水流条件,在物理模型试验的基础上结合天然实测资料,研究了老江坝分汊汇流区附近的水流条件,进而提出了改善其通航水流条件的优化布置方案。研究结果表明,调顺陆域岸线结合挖除洲尾的方法对改善分汊出口水流条件的效果较明显。
The first phase proposed project of Leshan harbor is located in the reservoir area on the right bank of the Minjiang I.aornukong avionics hub, near to the outlet of right branch of Laojiangba. Affected by the right branching ex- port flow, the proposed port area exist certain inclined flow and reflux flow, and have a certain impact on the ship into the port, berthing, loading, unloading operations and water depth maintenance of harbor basin. In order to clarify the naviga- ble flow conditions, combined with natural measured data on the basis of the physical model tests, flow condition of Lao jiangba and optimization layout program of improving its navigable flow conditions are studied. The research results show that regulating land area combined with the excavation of channel island tail can improve flow conditions of the outlet of right branch significantly.
