摘　　要：本文研究了超高层建筑内控法分段投测轴线的方法。比较了分段投测和直接投测的精度,证明分段投测的优越性,计算了分段投测的最佳高度,提出了内控网变形的调整措施。并结合工程实例,证明了这些方法的有效性。Based on the subsection inner-control method, this paper studied the precision of axes projection, and illuminated the advantages of subsection project through comparing the precision between the subsection project and the direct ones. Meanwhile, it calculated the best height of subsection project, and introduced the measures of correcting the distortion for control network. The related project cases have been proved that this way should be useful and effective
