Pile penetration is a very important engineering parameter in pile sinking operation of jacket platform. Insufficient penetration may lead to insufficient bearing capacity of pile foundation, resulting in platform instability and extremely serious safety accidents. In the process of actual pile sinking operation, the penetration is affected by many factors. In this paper, through relevant calculation and analysis, the influencing factors such as internal friction angle, pile diameter, hammer distance and hammer quality are studied, and the influence law of pile penetration is obtained. Finally, relevant suggestions are given in order to provide reference for engineering practice.

导管架平台裙座桩贯桩影响因素分析

沉桩贯入度是导管架平台沉桩作业中非常重要的工程参数。贯入度不足可能导致桩基承载力不足，造成平台失稳，造成极其严重的安全事故。在实际沉桩作业过程中，贯入度受到多种因素的影响。本文通过相关计算分析，研究了内摩擦角、桩径、锤距、锤质量等影响因素，得出了桩贯入度的影响规律。最后给出了相关建议，以期为工程实践提供参考。
