摘　　要：鸡心洲浅滩整治建筑物较多,但整治效果不明显,是赣江西支著名的碍航浅滩。通过对该河段的水动力条件和河床演变分析,揭示了该浅滩的成因和演变特点,确定了整治原则和方法,并通过河工模型试验进行了多个整治工程方案的对比研究,最终确定整治效果较佳的小曲率方案。经各典型年冲淤试验,鸡心洲浅滩段的航行条件可满足Ⅲ级航道标准。Jixinzhou Shoal is a famous navigation-obstructing shoal in the west branch of Gan River. Although there are a lot of regulation structures at the shoal, the regulation effect is not obvious at all. Based on the analysis of hydrodynamics and river-bed evolution, this paper reveals the formation causes and evolution characteristics of the shoal, determines the regulation principle and method, and carries out comparative study on several regulation schemes through river engineering model test, according to which, the small curvature scheme was selected at last. Based on the scouring & sedimentation test of different typical hydrological years, it is proved that the navigation condition at Jixinzhou reach can reach the grade three channel criterion.
