摘　　要：分析安徽省观测台网12套TJ-Ⅱ型体应变资料发现,其数据形态存在3类典型特征:一是数据连续漂移上升的年变化形态,日变化能记录到明显的固体潮汐;二是数据年变化形态同步于同井水位变化,体应变和水位的相关系数约为0.85;三是数据没有明显的年变化,数据形态多变。结合数据资料的内精度、钻孔环境、安装情况、干扰因素及产出资料显示的图像特征发现,3类典型特征主要和仪器、钻孔环境、安装质量关系密切。We investigate the data characteristics of volume borehole strain observatory in Anhui province including 12 sets of TJ-Ⅱvolume 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.
