摘　　要：从利用海洋废弃导管架出发,介绍为实现海洋平台导管架陆地和海上部分的对接,废弃导管架陆地部分与海上部分的主要测量内容和测量精度要求;分析导管架测量与常规测量比较存在的主要难点;提出几何测量方法较常规传统测量存在的误差传递积累和测量精度低而言,简便、易操作、精度高;介绍几何法测量的具体原理和计算公式,说明导管架桩腿之间距离以及导管架倾斜角度精确测量的详细步骤和计算方法,并对桩腿之间距离的误差、倾斜角度误差传播公式进行推导;结合实例说明导管架安装精确测量的过程,计算测量结果和测量误差,总结导管架安装几何方法测量的基本经验。Starting from the main role about surveying content and measuring precision used in the surveying that links up the jacket from onshore to offshore, the difficulty of jacket surveying compared with the routine measurement is analyzed and the geometry measuring is more convenient, operational and has high precision compared with the conventional tradition surveying method which has error transmits accmnulation and low precision;the concretely original of the geometry surveying and the formula are introduced to show the detail step and the computational method used in the tilt angle measurement and the distance measurement between platform legs, forevermore, we make a inferential reasoning as the distance error and the tilt angle error, explanted the precision measuring process of jacket installing, computation measurement result and measuring error by example, then we summary the experience of the geometry surveying method of jacket installing.
