摘要
针对自升式钻井平台在“踩脚印”过程中,桩靴位置发生横向滑移,会对平台结构造成破坏的问题,根据平台结构及桩腿的极限承载能力,计算出桩靴沿 x 轴0°、60°、90°、120°、180°方向滑移的极限距离;监测桩腿 RPD 值,总结得到桩靴在不同方向滑移距离与 RPD 之间的关系,为平台设计人员和操作人员提供参考。
In the course of “footprints” of jack-up drilling platform, the position of spudcan will slip horizontally. If the slip distance is too large, the platform structure will be damaged. The bow spudcan of the platform slides along the x -axis direction of 0°、60°、90°、120° and 180° respectively. According to the ultimate bearing capacity of platform structure and pile leg, the ultimate distance of spudcan slip was calculated. The relationship between the slip distance of spudcan in different directions and Rack phase difference ( RPD ) was obtained by monitoring the RPD value of pile leg. It provides meaningful guidance for platform designers and operators.
