Abstract:Using the removal-recovery method, the global atmospheric model and the pressure data of regional weather stations in the area around the Lanxin railway from 2012 to 2017, we calculate the influence of atmospheric load on the crustal deformation and gravity change in the 6 year period according to the atmospheric load theory. The results show that atmospheric load has an impact of about 1 cm on the vertical deformation of the Lanxin railway area, and less than 2 mm on the horizontal deformation. The impact on the vertical deviation is roughly 6 ms; on the ground gravity, the impact is roughly 6 μGal. The influence of atmospheric load on crustal deformation and ground gravity shows annual periodic and seasonal changes.
