黄梅台形变观测资料的短期干扰因素分析
|
摘要
利用黄梅台长期稳定、连续、可靠、精确的观测资料,应用EIS2000[1]地震前兆信息处理与软件系统及MapInfo软件系统,通过对比分析气象变化、人为干扰、仪器故障等非地形变信息和误差干扰因素,多方法分析、处理了台站水管仪、伸缩仪两套仪器定点形变观测资料。从资料分析结果中掌握某些基本常见的规律,为台站人员在日常资料处理中提供了有益的参考,以便更好地获得更高质量的观测资料。
Based on long-term stable,continuous,reliable and accurate observations of Huangmei Station,using the earthquake precursor information processing system(EIS2000) and MapInfo,an analysis is made of the observed data from the station's water gauge and extensometer,with respect to changes in weather,man-made interferences,equipment failure and other non-crustal deformation information and disturbing factors.The result provides a useful reference for station staff in daily data processing to facilitate better access to higher quality observational data.
