山东省交通厅海运局于1980年设计和建成了一座长100米的试验性重力式浅基沉管码头,至今情况基本正常。这种码头结构是一般重力式挡土墙与沉井基础的结合。以抽砂代替专用船机挖泥,以管柱代替基床抛石和底层方块,施工简化,造价降低。该港濒临渤海。据地质资料,由上而下表层1～3米为饱和状灰色粉砂,较松软;其下
In 1980, the Maritime Bureau of Shandong Provincial Communications Department designed and built a pilot gravity gravity submarine immersed tube wharf of 100 meters in length. Up to now, the situation is basically normal. This wharf structure is a combination of a general gravity retaining wall and a caisson foundation. Dredging instead of using a dedicated ship dredging machines, pipe columns instead of the riprap and the bottom of the square box, construction simplification, lower costs. The port is on the verge of the Bohai Sea. According to geological data, 1 to 3 meters from the top to the bottom of the saturated gray silt, softer; under
