选用2017年4月到2019年4月乌兰浩特地震台DSQ型水管倾斜仪观测数据,总结自然环境、人为及场地干扰事件,并挑选典型干扰事件进行详细分析。结果表明,观测数据受自然环境干扰时主要表现为噪声大现象,受人为干扰时会出现数据突跳,受场地环境干扰时会出现数据畸变。通过对各类典型干扰的分析,期望为同行就DSQ型水管倾斜仪观测数据的干扰识别及处理提供参考。
The observation data of DSQ water-tube tiltmeter at Ulanhot Seismic Station from April 2017 to April 2019 are selected to summarize the natural environment, human interference, and site interference events. Typical interference events are selected for detailed analysis. The results show that when disturbed by the natural environment, the observation data mainly show the phenomenon of large-amplitude noise; when disturbed by human interferences, the observation data show the phenomenon of data jumping; and when disturbed by site environment, the observation data show data distortion. Through the analysis of various kinds of typical interference, it is expected to provide a reference for peers to identify and process the interference in observation data of DSQ water-tube tiltmeter.
