摘要
This paper draws the vertical deformation map of Beijing-Tianjin region by using the inter-city railway leveling data. According to the map, the repetition leveling shows the same abnormal vertical deformation phenomenon of “southern area rose and northern area fell” as that of the capital region at the corresponding period. Further analysis indicates that it is necessary to enhance the deformation monitoring of the capital region and even the North China to provide scientific basis for deformation-developing tendency judgment.
