S工程位于我国某大港的东侧,是在淤泥质浅滩上开辟的一个港口,拟建中的港口工程分一、二两期,第一期有回填、护岸、防波堤和滑道;第二期有接长防波堤、建造浮码头和开挖港池航道等(见图1)。本文的研究内容是:在建成护岸、防波堤工程后,在不开挖港池的情况下,港内自然回淤情况,包括港内不同部位随时间变化的淤积状况以及港池挖至-5米时回淤情况。根据以上研究内容,组织了港区潮流的观测,结合过去对这一地区波浪、泥沙运动的研究成果和淤泥质海岸的保滩促淤工程的研究成果,开展了上述任务的研究。
S project is located on the east side of a major port in China and is a port opened up on silt shallow shoals. The proposed port project will be divided into two or two phases with the first phase of backfilling, revetment, breakwater and chute. The second phase There are long breakwaters, the construction of floating pier and excavation of the harbor channel, etc. (see Figure 1). The research content of this article is: After the revetment and breakwater project are completed, the natural siltation in the port, including the siltation of different parts of the port over time, and the digging of the harbor to -5 meters Silt situation. Based on the above research, we have organized the observation of the tidal current in the port area, and combined with the research results of wave and sediment movement in this area in the past, and the research results of the tidal flat and silting project of muddy coast.
