摘　　要：以武汉新港阳逻港区三作业区一期工程起步阶段工程为实例,针对工程区域局部有矶头分布、基岩埋深浅且岩面陡、水位差和水流流速大、使用荷载大等建设条件,对码头结构选型、桩基布置与优化、稳桩等问题进行了深入分析与研究,并通过基桩自平衡法验证桩的竖向抗压极限承载力。工程实施后效果良好,相关结论可供类似工程建设条件的码头结构设计参考。Taking the start stage project of the three areas phase玉project of Wuhan Newport Yangluo Port as an example,in view of the construction conditions,such as the engineering area local angeles head distribution,the shallow buried depth of bedrock and steep rock surface,the large water level difference and flow velocity,and large service load,we analyzed and studied the selection of pier structure,pile foundation arrangement and optimization,and the stabilizing piles,and verified the vertical compressive ultimate bearing capacity of pile by the pile self-balancing method.After project implementation effect is good,the relevant conclusion can be used as reference for pier structural design under similar engineering conditions.
