| Abstract: | In this paper, the observed strain data recorded by three stations of Shandong Province from 2007 to 2011 are seleted for analysis on the integrity, intrinsic quality,and interference factors. The results show that：①The observation data of cave strain kept the continuous and integrity;②The annual zero drift of each instrument met the design requirements;③The rel- ative error of M2 wave amplitude factor and relative noise level were Class I strain monito- ring ;④ Observation quality was been improved significantly when the instruments had been updated;⑤The cave strain observation was mainly affected by the instrument repair, air pressure, rainfall and environment change. |
| Keywords: | cave strain quality analysis annual zero drift error of tidal factor relative noise level disturbance |
