考虑隔水导管群桩基作用的导管架平台强度分析方法

STRUCTURAL ANALYTICAL APPROACH OF JACKETPLATFORMS CONSIDERING PILE FOUNDATIONEFFECT OF CONDUCTORS

本文探讨了导管架平台结构强度分析一种改进方法。在该方法中，考虑了隔水导管群刚度和桩基作用，同时考虑了隔水导管之间以及隔水导管与主桩之间的群桩效应以及上部结构－桩－土相互作用。通过对某六腿导管架平台的分析表明，改进方法可以给出比常规方法更合理的结果。

This paper describes an improved structural analytical approach of the jacket platform in which the stiffness and pile foundation effect of conductors on jacket structure is taken into consideration. Supersturcturepilesoil interaction and pile group effect between conductors and main piles are also considered in the approach. It is shown by an analytical example of a sixlegged jacket platform that the improved approach gives more reasonable results than the regular analytical approach.
