摘要
提出一种适用于陆域狭窄、码头悬臂段大、地震液化条件下的前板桩高桩结构形式,主要结构特征为:前板桩选用钢管型组合钢板桩,其后结合PHC叉桩锚碇设高桩梁板结构,高桩结构后方设挡土板和减压棱体,钢板桩在极端低水位处设泄水孔;可液化的粉砂层地基土进行水下振冲密实处理。
This paper presents the structure of front sheet pile wall with rear piled platform, which can be used for narrow land area, large cantilever and silt foundation with serious liquefaction conditions. The main features of the structure are as follows： The front sheet pile wall is steel tube type combined steel sheet pile; The rear part is piled platform with PHC fork pile anchorage; The poling board is set at the back of the piled platform; The drainage hole is set in the steel sheet pile around the extreme low water level; The silt foundation is treated by vibration shock process under water.
