It is quite important to monitor the ground vibration influenced by the construction at Shanghai Synchrotron Radiation Facility (SSRF), because the SXFEL is just in the north of SSRF and the nearest distance is only 20m. In this paper, the results of ground vibration measurement during the construction period at SSRF experimental hall, tunnel and experimental room near the SXFEL site are shown. Vibrations at different hours, frequency bands and directions are discussed to provide more detailed information on the influence of SXFEL construction to SSRF.
