摘要
在中国海域已有多座无人值守平台,单立柱三裙桩型式导管架平台是其中的一种结构型式,底部结构为三角形.三角形防沉板稳性设计与常规导管架稳性设计有区别,主要包括非常规结构的环境荷载方向选取,插桩过程中桩产生的环境荷载,以及打桩过程中桩传递给套筒的力.利用本文所述方法可为三角形防沉板坐底稳性设计提供参考.
Abstract
There are already some unmanned platforms in China Seas,one legged with 3 sleeves jacket platform is one type of unmanned platforms,and the platform bottom is triangular.The triangular shape mudmat stability design is different from the conventional jacket mudmat.The main differences include environmental load directions selection,the pile environmental loads during pile installation,and the pile loads on sleeve during pile driving.The method described in this article can provide a reference for the triangular mudmat stability design.
