Abstract
The dataset is related to the ground surface and structure deformation during the construction of Chongqing subway line 9 in four months. The tunnel was constructed using drilling and blasting method as well as the tunnel boring machine (TBM). A systematic monitoring system was set in the site and it included monitoring points for ground subsidence, building settlement, vault deformation and the tunnel horizontal deformation. The deformation data in this article was measured using surveying in the site and it can be reused to validate numerical simulation results and guide the similar engineering project in the nearby area.
