摘　　要：结合海工码头使用荷载大、出运工艺复杂的特点,对软弱地基上某海工码头接岸结构的选型及设计进行论述分析,从地质条件、施工条件和使用要求等方面论证选用整体卸荷式板桩结构,前墙板桩选用灌注桩排桩形式,承台下灌注桩采用长短桩间隔布置,使得结构受力更为合理,解决了软弱地基上接岸结构同时承受较大竖向和水平使用荷载的问题,采用塑性混凝土桩进行排桩地连墙的堵缝处理,效果明显;同时对土压力计算与分配、m法模拟桩土相互作用等相关计算进行探讨,供类似工程参考。Combined with the characteristics of large load and complex transportation process of marine wharf,the selection and design of land-connecting structure of a marine wharf on soft foundation were analyzed.From the aspects of geological conditions,construction conditions and operating flux needs,a sheet-pile structure with a load-relieving slab was selected.The front wall sheet pile was in the form of a cast-in-place pile row pile,and the cast-in-place pile under the cap was arranged with long and short pile intervals,making the structure more reasonable and solving the problem of the land-connecting structure on soft foundation bearing large vertical and horizontal service loads at the same time.The plastic concrete pile was used to plug the joint of the pile-row diaphragm wall,and the effect is obvious.Additionally,calculations and simulations such as earth pressure calculation and distribution and m-method to simulate pile-soil interaction were discussed for similar projects reference.
