Abstract: The leveling measurements of acceleration tendency change at Daixian station since May 25th, 2013 is credible, showing normal fault activity. According to environment investigation, it includes some interference factors. Due to the big wind during the leveling measurements in the afternoon, there is certain influence on the results, but the impact is random. The result fluctuates near the base value and does not show any trend change. The point BM3 was maintained during September and October, 2012, and cracks appeared in 2013, indicating that the stability of point BM3 is poor. In addition, the change of recorded program only changed the way of data record and did not affect the observation results during the same period.
