影响康定地震台形变观测数据的主要干扰因素

Main interfere factors affecting the precise of deformation observation data in Kangding Seismic Statio

对康定地震台地质环境及仪器安装作了简要介绍。整理、分析了康定地震台JB3M金属水平摆倾斜仪及VS型垂直摆倾斜仪在日常工作中观测数据受到的干扰影响,截取了相关干扰记录波形并且作出了对应说明。为台站工作人员在日常观测数据处理中提供实例参考,为地震分析预测人员提取康定台形变观测数据时剔除其中的干扰因素提供有效依据。

The geological environment and the installing of deformation observation meters in Kangdin Seismic Station are introduced in this paper. We put in order and analyze these observation data of JB3 M tilt meter and compare these data with the data of VS vertical pendulum tilt meter installed in same seismic station. The interfere effecting for both meters are discussed. Several examples of the observation curves on interferes are described. Our explanations can be helpful to operators in seismic station and to the person for the earthquake prediction
