一种新型圆沉箱在墩式码头中的应用

Application of a new type of round caisson in dolphin wharf

针对沉箱重力墩式码头设计中沉箱吃水大、结构所受波浪力大、地基应力大的问题,介绍一种瓶形圆沉箱结构。该结构沉箱下部直径大、上部直径较小,外形如瓶状,通过工程实例进行技术方案以及案例分析对比研究。结果表明该沉箱可有效减少吃水,用于墩式码头结构中,可降低波浪力、地震力等外力,从而减少地基应力。

Aiming at the problem that the caisson draft is large, the structure is subjected to large wave force and the foundation stress is large in the design of the caisson gravity pier type wharf, a bottle-shaped caisson structure is introduced.The structure caisson has large diameter at the lower part and a small upper diameter, and the shape is like a bottle. Through the engineering example, the technical scheme and case analysis and comparative study are carried out. The results show that the caisson can effectively reduce the draft, used in the dolphin wharf structure, can reduce the external forces such as wave force and seismic force, thereby reducing the foundation stress.
