精密水准网是城市测绘基准重要的基础设施。本文结合2011年上海市开展的精密水准网复测项目，首先介绍了上海市精密水准网复测数据处理过程，然后说明了采用4种平差模型及数据解算结果。在此基础上，通过比较分析4种平差模型的解算结果，获得了此次精密水准复测的最终成果数据。同时，本文还比较分析了上海市历年水准复测的成果数据，并通过拟合的方式得到一些关于上海地区地面形变的有益结论。

Precise leveling network is an important infrastructure of city surveying and mapping. This paper first in- troduced the data processing of the precise leveling network in Shanghai which is carried out in 2011, and then described the four adjustment model and the results of data solver. On this basis ,the results of the four adjustment model solver was been comparative analysis to obtain the final results of the precise leveling network surveying project. The same time, the comparative analysis of the leveling data over the years in Shanghai had been done, and through this way to get some use- ful conclusions on the surface deformation of the Shanghai area.
