Analysis of Influencing Factors of Pile Penetration of Jacket Platform Skirt Pile

Abstract

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.
