摘　　要：赣江主支象山枢纽为通航河流枢纽,工程施工期妥善处理船舶通航问题尤为重要,应结合工程分期施工方案,提出对应的通航方案。一期工程施工由临时航道通航,二期工程施工由船闸通航。本文针对一期工程施工临时航道通航水流条件问题,采用数值模拟计算方法,建立二维水动力数学模型对不同流量条件下的水流流态进行计算分析。结果表明:在施工一期时段内临时航道的水深和流速均满足相关要求。The Xiangshan hydro-junction locates on the main branch of the terminal section of Ganjiang River,and is a navigable river control junction.It is particularly important to properly deal with the navigable problem during the construction period.Therefore,a corresponding navigation scheme should be proposed according to the stage construction plan.During the first stage of the project,a temporary channel will be used for navigation,while the ship locks will be used in the second stage.This article focuses on the navigable flow conditions of the temporary channel during the first phase.The flow patterns under different flow conditions are calculated and analyzed by establishing a two-dimensional FVM hydrodynamic mathematical model.The results show that the water depth and velocity of the temporary channel in the first stage of the project meet all the relevant requirements.
