摘　　要：在高大建筑施工中,高精度的标高传递测量是施工测量的难点之一。本文以杭州湾跨海大桥高大索塔标高传递测量为例,提出了全站仪垂直向上测距法高差测量,较好地解决了高大索塔施工标高控制的问题,实践证明该法是恶劣环境下高大建筑物高程传递测量的一种较为有效的方法,可以满足施工的高精度要求和保证工期。In the high and large-scale structure project, the higher precise elevation-transferring＇method is one of the most difficult section in the project surveying. This paper take the elevation-transferring method of HangZhou Gulf Bridge for example, brought forward the elevation difference surveying which uses the total-station upward to measure the distance vertically, solved the elevation controlling of the high and large-scale cable-support tower, practice maked it a better valid method for the elevation-transferring of the high and large -scale structure in bad circumstance, and it can meet the higher precision of project and complete the project on time.
