摘　　要：常规基于人工的坐标分解计算,在应对逐渐提升的建造要求及特殊产品的应用需求时,存在效率不高、人为误判等情况,本文通过对局部坐标分解应用进行研究及自动坐标分解与重新定向,有效解决了过山车类复杂结构建造尺寸精度管控过程中数据的修正及合格判定问题,为同类复杂空间钢结构的高精度测量检验偏差修正积累了丰富的应用经验。The conventional method of coordinate decomposition calculation based on manual operation is not efficient and there may be erroneous judgement due to human fallibility in responseing to the gradually increasing construction requirements and the needs of special products application.In this paper,the problem of data correction and qualification evaluation in the dimensional accuracy control for the construction of the complex structures similar to“roller coaster”is effectively solved with the help of automatic coordinate decomposition and redirection,which has accumulated a comprehensive experience of project application in the high-accuracy surveying,inspection and deviation corrections for the similar complex spatial steel structures.
