摘　　要：选取位于陕西汉中地区的汉中形变台(南郑813厂)和宁强形变台2017—2021年DSQ型水管倾斜仪和SS-YⅡ型洞体应变伸缩仪的观测数据,通过对2个台站共4套仪器的连续率、完整率、年零漂、相对噪声水平和资料质量评定内精度等技术指标进行计算和对比分析,对陕西汉中地区定点洞体形变台站观测数据质量做出科学评价,以期为本区域无人值守地震台站监测效能评估和地震预测预报研究提供参考。The observation data of DSQ tube tiltmeters and SS-YⅡextensometr at Hanzhong deformation monitoring station(Nanzheng 813 plant)and Ningqiang deformation monitoring station in Hanzhong,Shaanxi Province from 2017 to 2021 were selected.Through the calculation and comparative analysis of the technical indicators such as the continuity rate,integrity rate,annual zero drift,relative noise level and internal accuracy of data quality evaluation of four sets of instruments at two stations,This paper makes a scientific evaluation on the quality of observation data of fixed-point tunnel deformation stations in Hanzhong,Shaanxi Province,and provides a reference for the evaluation of monitoring efficiency of unattended seismic stations and the study of earthquake prediction and prediction in this region.
