Abstract: This paper analysis characteristics of the Hushi shoal and the main hinderance of navigation.Engineering comparation tests have been done based on the recognization of shoal nature. It is suggested that channeling, spit cutting works, stur-dike should be done in order to guarentee safe navigation under both moderate water level and low water level.

Key words: Hushi shoal, channel regulation, model test;

摘要： 分析了葫市滩河段的滩险特性、碍航原因 。按照“扩大中洪水过水断面，减小流速、比降”的原则，提出 挖槽、切嘴、疏浚等工程措施，通过河工模型试验，表明整治流量下，该滩的航行条件显著改善，流速、比降满 足要求的航宽大于17m ，船舶可自航上滩。
