在淤泥质软弱地基上的海港码头,以往的实践经验是采用高桩结构.但建设地附近砂石材料丰富,施工单位不具备搞桩基码头的设备和技术力量,而对重力式码头则有较成熟的施工经验,这样,在设计上考虑挖除部分淤泥质土,换以砂,采用底宽稍大的空心方块和空斗胸墙;在施工中采取施工顺序分段平行,控制加荷速率等措施,使淤泥质软弱地基的承载力仅为8t/m~2的情况下,建造重力式码头成为可能。

In the port of silt on the weak foundation of the harbor, the past experience is the use of high-pile structure, but the construction site near the rich sand and gravel, the construction unit does not engage in pile-based terminal equipment and technical strength, while the gravity terminal there More mature construction experience, so that in the design to consider digging part of the muddy soil, replaced by sand, using the bottom width slightly larger hollow blocks and air chest wall; in the construction sequence to take the construction sequence parallel to control the loading rate And other measures to make silt weak foundation bearing capacity of only 8t / m ~ 2 case, the construction of gravity wharf becomes possible.
