Abstract We investigate the data characteristics of volume borehole strain observatory in Anhui province including 12 sets of TJ-Ⅱ volume borehole strainmeters. The comprehensive analysis of the volume strain summarizes the three typical characteristics, including the continuous- drift-upward annual change pattern, water- level-synchronization annual change pattern, and no significant annual change. Based on the internal precision of the data, drilling environment, installation situation, interference factor, and image feature of the output data, etc., three typical characteristics are closely related to strainmeter, borehole, and installation quality.
