信阳地震台DSQ水管仪主要干扰因素跟踪研究

The Tracking Analysis of Main Interference Factors of DSQWater Tube Tiltmeter in Xinyang Seismic Station

DSQ水管仪通过记录山洞台基的垂直位移来反映地壳形变变化,选取本台DSQ水管仪2017年整年连续、可靠的定点形变观测数据,总结时段内影响DSQ水管仪观测资料的主要干扰因素,在形态上主要表现为大幅度阶跃变化,主要从自然因素、仪器本身状态、人为干扰等三个方面进行具体分析,并进行干扰因素总结,为长期稳定观测累积有效经验,为有效利用数据提供基础,有利于异常跟踪分析工作的切实进行。

The DSQ water tube tiltmeter reflects the crustal deformation change by recording the vertical displacement of the cave foundation.Selecting the continuous and reliable fixed-point deformation observation data of this DSQ water tube tiltmeter for the whole year of 2017,this paper summarizes the main interference factors affecting the observation data of DSQ DSQ water tube tiltmeter in the period of time,which mainly shows a large step change in morphology,mainly from the self-contained point of view.However,the factors,the state of the instrument itself and the human disturbance are analyzed in detail,and the disturbance factors are summarized,which can accumulate effective experience for the long-term stable observation,provide the basis for the effective use of data and facilitate the practical work of anomaly by the tracking analysis.
