近年来，随着经济的发展和土地资源的紧缺，超高层建筑越来越多，高度也越来越高，施工测量的难度也越来越大，如何准确地实现超高层建筑平面控制网竖向传递成为超高层建筑施工测量的难点和重点。垂准仪法受环境影响小，投测距离大，效率高，误差小，是目前超高层建筑平面控制网竖向传递内控法的主要方法，本文以某超高层建筑为例，论述了垂准仪法平面控制网竖向传递的具体实现及精度检核方法。

In recent years,with the development of economy and the shortage of land resources ,there are more and more super high-rise buildings,They become higher and higher ,construction survey becomes more and more difficult , How to accurately realize plane high-rise building control network vertical transmission has become the emphasis and dif -ficulty in the super high-rise building construction measurements .Collimator method is less affected by the environment , projection distance ,high efficiency ,small error,is the main method for plane high-rise building control network vertical transfer control method ,Taking some super high-rise building as an example ,this paper describes the use of collimator in the transfer of horizontal control network and the accuracy assessment .
