摘　　要：随着社会经济的迅速发展,高层建(构)筑物越来越多,精确测量出这些建(构)筑物的高度并为施工建设和安全监测提供可靠依据显得尤为重要。针对全站仪精确悬高测量的两种具体情况,许多学者对其进行了探讨并提出了一些改进方法。本文首先介绍这些精确悬高测量改进方法的不足与缺陷,然后提出了一种精确悬高测量的新方法,并对其进行公式推导和精度分析,最后通过两个实例证明了此方法的可行性及优越性。With the rapid development of socio-economic,high-rise buildings are more and more.Accurately measuring the height of these buildings for the construction and safely monitoring to provide a reliable basis seem particularly important.Precise REM utang total station for two specific circumstances were discussed by many scholars with some improvement methods.This paper firstly describes the deficiencie and defects of these improved methods,and then proposed a new method of high-precision REM,and carried on the formula derivation and the analysis of accuracy,finally proved the feasibility and advantages of this method through two examples.
