我国秦皇岛港、大连港、石臼港均建有由预制沉箱筑成的重力式突堤码头,这种码头由沉箱构成的靠船墩不仅要承受靠船力、系缆力,而且还要承受波吸力、波压力的作用,因此靠船墩要有足够大的尺寸,这就要求有相应大的预制场地和设备能力。但场地 China’s Qinhuangdao Port, Dalian Port, Shijiu port built by the prefabricated caissons built by the gravity jetty, which is composed of caisson by the caisson not only to withstand the ship’s power, mooring force, but also to bear the wave suction , The role of wave pressure, so by the pier must have a large enough size, which requires a correspondingly large prefabricated site and equipment capacity. But the venue
