文章研究了某高桩码头发生桩基倾斜、开裂现象的原因，并提出应对措施。通过现场检测及计算复核结果显示，该码头桩基倾斜、开裂的主要原因是施工期码头边坡滑移所致。且边坡滑移时，近岸侧桩受力最大，离岸侧桩受力逐渐减少，其受力并不均等；使用期间岸坡在自然环境的作用下调整密实并自然恢复到稳定状态，构件受力在正常使用范围内。提出对高桩码头的岸坡进行边坡稳定计算时，除用土的力学指标平均值在淤泥层厚度最大的截面进行边坡稳定验算外，对取样得出土的力学指标较低的截面也需进行稳定性验算，施工期还要根据施工工艺荷载进行边坡稳定验算。

The causes of pile inclination and pile cracks of a high?piled wharf were studied in this paper, and the countermeasures were proposed. Through field testing and rechecking, the calculation results show that the main reason of pile inclination and pile cracks is the slope sliding of wharf during construction period. When the slope is slipped, the force exerted on the inshore side pile is the largest, and it is gradually reduced on the offshore side. Its force is not uniform. During the application period, the slope is adjusted to the compact state under the ac?tion of the natural environment, and it is stabilized after natural restoration. The force is within the normal range. It is proposed that in addition to the slope stability checking calculation on the cross?section with the largest silt layer thickness by the average mechanical indexes, the checking calculation of slope stability is also necessary when the soil mechanical indexes are relatively low. It also applies the construction load for checking the slope stability calcu?lation during construction period.
