康定地震台VP型垂直摆倾斜仪常见干扰分析

Analysis of the Common Interference Factors of VP Vertical Pendulum Tiltmeter in Kangding Seismic Station

收集并整理康定地震台VP型宽频带垂直摆倾斜仪运行以来的观测资料,分析识别观测资料中存在的各种干扰因素及其特征,认为降雨、降雪、强日照、人工干扰、观测系统类干扰是影响仪器观测的主要因素。对新运行仪器的干扰因素进行准确的识别,能够积累观测经验,有助于提高观测质量,进一步提升异常判别的准确性。

In this paper,the observation data of VP vertical pendulum tiltmeter in Kangding seismic station since its operation are collected and sorted out. Various interference factors and their characteristics in the observation data are analyzed and identified. It is considered that rainfall,snowfall,strong sunshine,artificial interference and observation system interference are the main factors affecting the instrument observation. It can accumulate observation experience,improve observation quality,and further improve the accuracy of anomaly identification by accurately identifying the interference factors of new instruments.
