京津水准复测与垂直形变特征

Repetition Leveling and Vertical Deformation Characteristic of Beijing-Tianjin Region

利用京津城际铁路水准测量资料,绘制了京津地区垂直形变图,发现京津城际铁路水准复测结果同样也出现了与首都圈地区同期水准测量相一致的"南升北降"垂直形变异常现象。分析认为应加强首都圈乃至华北地区的形变监测,为判定形变发展趋势提供依据。

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.
