三峡枢纽运行中后期，上游引航道隔流堤将永久船闸和升船机的航道包括在内（即大包方案）为技术设计专题研究论证的优选方案。在此基础上提出了船闸从堤外取水的设想，从而可以较好地解决堤内往复流和水位波动、航道内淤积等航运的关键技术问题。流态试验的结果表明，如将三期纵向围堰加高到１４８米高程，右电厂直接从围堰右侧进水，则能明显地改善坝前的流态，对保证枢纽的过流能力和增加发电量都有重要意义。
In the mid-to-late period of the operation of the Three Gorges Project, the diversion embankment of the upstream inflow channel will include the navigation channel of the permanent ship lock and the ship lift (ie, the bale package) as a preferred solution for the technical design research and demonstration. On this basis, the idea of taking water from outside the embankment is proposed, which can solve the key technical problems of reciprocating flow and water level fluctuation in the embankment and siltation in the waterway. Flow test results show that, if the three longitudinal cofferdam elevation to 148 meters elevation, the right power plant directly from the cofferdam into the water, it can significantly improve the flow in front of the dam, to ensure that the hub of the flow capacity And increase the amount of power generation are of great significance.
