Abstract
This paper first introduces geological background of the Three Gorges Reservoir and then reviews composition of the Three Gorges GNSS deformation monitoring network. The GNSS monitoring strategy from 2010 to 2012 is elaborately analyzed from technology design, field observation, data processing and deformation analysis. vertical deformation showed a subsidence trend in around the dam and near the Yangtze River，Vertical deformation showed a uplifting trend in TG14 station and TG13station. The results show that the three-year’s variation of the crustal deformation is small, and then the surface structure variation is stable in present around the Three Gorges Reservoir area.
