Outline
After the operation of Wudongde, Baihetan, Xiluodu and Xiangjiaba hydropower stations (XJB), the channel conditions in the lower reaches of the Jinshajiang River have been greatly improved, which prompts the ships in this section of the river to increasingly develop towards larger sizes. When encountering the dry inflow from the Jinshajiang River, the water depth of the channel from Xiangjiaba to Yibin River is shallow, and the passage of large cargo ships is difficult, which affects the shipping efficiency of the river section. By analyzing the relationship between the loading capacity of the main ship types and the discharge from XJB, the optimal seaworthy discharge of the river section is obtained. Combined with the actual operation of the ships at the wharf, a tidal shipping scheduling model was established by intermittently releasing the seaworthy flow of XJB, and a variety of schemes were proposed to simulate the calculation. The results show that the XJB can increase the navigation time of large ships, increase the average cargo volume of a single ship by 16%, and increase the power generation head by 0.31 m, and has a positive impact on promoting the exchange of water bodies in the reservoir area. The research results can provide references for regional shipping scheduling management.
