淮北台DSQ型与SSQ-2I型倾斜仪观测资料的对比分析

Comparative Analysis of the Observation Data between DSQ Type and SSQ-2I Type Tiltmeter of HuaiBei Station

对淮北台DSQ型水管和SSQ-2I型水平摆倾斜仪观测资料质量从一般指标和内精度指标进行定量判定,结果表明水管仪观测质量较高,稳定性不及水平摆倾斜仪,观测数据均受大风和降雨影响。因仪器工作原理、技术参数等因素不同,记录到同震形变波在响应延迟、最大振幅和形态特征等方面存在一定差异。

There was a measurable judgment about the observation data between DSQ water tube tihmeter and SSQ-2I horizontal pendulum tihmeter, which was judged from the aspects of general indicators and inner-accuracy. The results showed that the observation quality of DSQ was better than that of SSQ-2I, whose stability was better than DSQ; the data of DSQ and SSQ-2I were both interfered by gale and rain. Owing to the difference in working principles, technical parameters and so on, the recorded co-seismic deformation waves of DSQ and SSQ-2I were different in terms of operating lag, maximum amplitude, morphological feature, etc.
