某高桩码头断桩现象分析

介绍某高桩码头靠岸侧斜桩在桩帽处断桩现象,分析认为在斜桩轴向力的水平分力作用下,斜桩与桩帽的连接强度不足是断桩主要原因,软土地基、施工质量和堆场超载也是断桩原因,建议桩的结构计算时要进行斜桩与桩帽或横梁连接计算。

Analysis of factors causing damages to oblique bearing piles of wharf

The oblique bearing pile nearby shore in a wharf was damaged at the joint of the oblique bearing pile and the pile cap. It is thought that under the horizontal component of the axial compressive force of the oblique bearing pile, the lack of jointing strength of the oblique bearing pile and the pile cap is the major reason for the damage. Besides, the soft ground, construction quality of the joint and overload of storage yard may also cause the damage. It is suggested to carry out the calculation for the connection of the oblique bearing pile and the pile cap or the transverse beam.
