通过建立三峡工程上游引航道近闸区域的三维水力学计算模型,计算了增加一线船闸后上游引航道内通航水流条件,分析了145、175m两种典型通航水位条件下三线船闸不同充水组合对通航水流条件的影响。结果表明,三线船闸运行时,各船闸单线充水均可满足规范通航要求;两线或三线船闸同时充水时,上游引航道内部分区域不能满足通航要求,尤以145m水位时为甚,可通过错时充水的方式来满足通航水流条件的要求。
Through the establishment of a three-dimensional hydraulic calculation model of the upstream approach channel of the Three Gorges Project, the navigation flow conditions in the upstream approach channel after the addition of the first line ship lock were calculated. The effects of different water-filled combinations of the three-line lock at 145,175 m on navigation Influence of water flow conditions. The results show that when the three-line shiplock is running, the single-line water filling of each shiplock can meet the requirements of normal navigation. When the two-line or the third-line shiplock are filled with water at the same time, some areas in the upstream approach channel can not meet the navigation requirements, especially when the 145m water level is exceeded Wrong way to fill the water to meet the requirements of navigable water conditions.
