摘　　要：过渡段的施工过程包括陆地建造和海上安装两部分。过渡段在陆地卷制接长时,上部直管段纵缝要避开上部组块立柱底部管段纵缝,中间过渡段要避开导管架钢桩工作点处纵缝。过渡段海上安装时,要以组块底部实测跨距报告为依据,通过计算调整,保证钢桩切割、过渡段安装完毕后直管段跨距与组块实际跨距相同。以国内某项目为例,详细介绍过渡段的陆地建造和海上安装流程。The construction process of the transition section includes two parts,land construction and offshore installation.When the transition section is rolled on land,the longitudinal seam of the upper straight pipe section must avoid the longitudinal seam of the pipe section at the bottom of the upper block column,and the middle transition section must avoid longitudinal seam at the working point of the jacket steel pile.For offshore installation of the transition section,the measured span report at the bottom of the block shall be used as the basis.Through calculation adjustment,the span of the straight pipe section after the cutting of the steel pile and the installation of the transition section are the same as the actual span of the block.This article uses a domestic project as an example to detail the land construction and offshore installation process in the transition period.
