在浅埋坚硬岩层或坚硬黏土层的地质条件下，码头后轨道梁采用打入式钢管桩结构。针对不同地质情况，岩层地基桩尖采用开口形式，坚硬黏土地基采用混凝土封堵的全闭口形式，以适应地质的复杂变化，有效解决设计桩长的选择和沉桩控制等问题。经过静载试验验证效果良好，为类似地层提供借鉴经验。

Under hard rock or hard clay geological conditions with shallow buried depth, the driving steel tubular pile is used in the rear rail beam of berth. For different geological conditions, the open type tip is applied under hard rock foundation, while concrete block full closed tip is applied under hard clay foundation. It is adapt to the complex geological changes, and make an effective solution to the pile length design and driving control. The design is proved effective by static load test, and serving as references for design of similar projects.
