钢筋混凝土沉箱作为海上工程的主体结构,在我国北方沿海重力式工程中广泛采用。这种结构的主要优点是简化水上施工,缩短水上作业时间,沉箱在陆上予制后,浮运至施工位置沉放安装,尔后进行箱内填料,即可形成工程主体。施工时,一般无需大量水上施工船机,减少水上施工的复杂性。在陆上予制时,便于采用机械化,提高施工速度及质量;同时,沉箱结构整体性好,抗地震性能好,地基应力小,
As the main structure of offshore engineering, reinforced concrete caissons are widely used in the coastal gravity engineering in northern China. The main advantage of this structure is to simplify the water construction, shorten the water work time, caissons on land to system, floating to the construction site sink installation, and then fill the box, you can form the main project. During construction, there is generally no need for a large number of marine construction ship machines to reduce the complexity of water construction. In the land to the system, easy to use mechanization, improve the construction speed and quality; the same time, the overall structure of the caisson good anti-seismic performance, the foundation stress is small,
