自升式钻井船升船作业时，桩脚基础遇到砂－粘层状地基，即存在潜在刺穿的危险。基础刺穿的发生，会严重影响钻井船的安全作业。本文拟通过分析目前常用刺穿分析方法在渤海石油开发区的应用情况及土质参数的选取问题，找出适合渤海石油开发区土质特性的刺穿分析方法，以避免发生危险。
Jack-up foundations encounter a sand-viscous bedlike foundation when jack-up rigs are being lifted for boarding operations, posing the potential for piercing. The base piercing can seriously affect the safe operation of a drilling vessel. This paper intends to find out the piercing analysis method suitable for the soil properties of the Bohai Oil Development Zone by analyzing the application of the commonly used piercing analysis method in the Bohai Oil Development Zone and the selection of soil parameters to avoid the danger.
