摘　　要：耙吸船由于其船型特点,受到风、流及涌浪的影响,布线、耙头下放深度都将时刻发生变化,直接导致开挖质量以及扫浅生产效率降低。结合日照港石臼港南区深水航道一期工程,对设备进行改进,对不同浅点采取不同的扫浅形式,对其效果进行分析,总结出一套大型耙吸船扫浅施工工艺。结果表明,通过改进耙齿、立板、制作耙平器等设备,有效解决了耙吸船扫浅效率低的问题,有助于在类似工程推广使用。The trailing suction hopper dredger(TSHD)that has different characteristics of the ship type is affected by wind, current and swells. Its wiring and the rake head will be changed from time to time to directly reduce the excavation quality and dredging the shallow point. Taking the phase I project of the deep-water channel in the southern area of Shijiu Port, Rizhao Port, we improve the equipments, carry out the effect analysis of different construction methods adopted for different shallow points, and summarize a set of dredging shallow point construction technology for TSHD. The results show that improving rake teeth, vertical plate, and making plough can effectively solve the problem of low dredge shallow point efficiency of TSHD,and be popularized and used in the similar projects.
