摘要
通过抽取我台DSQ水管倾斜仪2008年至今的数字化观测资料,总结了现阶段影响DSQ水管倾斜仪资料的干扰因素,从自然和人为两大类进行了概括。由于我台地处西北,目前仪器受到雷雨天气、气压突变的影响最明显最频繁,反映在数据曲线上是毛刺和抖动,2010年8月采用增加分隔门的方法后自然干扰有所减轻。突然停电和来电会对水管仪数据造成脉冲状干扰。此外同槽安装仪器的互相影响、仪器工作状态的影响、以及各种人为干扰都做了小结。
Based on the observation data of DSQ tiltmeter from years 2008,the main interference factors are summarized,which included both natural and human factors.Because of the location of the station,the instrument is influenced by the thunderstorm weather and pressure mutations most frequently,which obviously reflected on the data curve is the burr and jitter.The method of increasing separation door was used to reduce natural disturbance in August,2010.Suddenly power outages or power-up can also cause pulse-shaped interference.In addition,the mutual influence of the two instruments installed in the same groove,the influence of the status of the instrument,and the influence of all sorts of human disturbance are all summarized in this paper.
