摘要
本文通过分析宽城地震台体应变仪自运行以来所有的观测数据,对宽城地震台体应变仪运行良好的区段(2005年-2008年)的动态特征进行分析研究,在此基础上对影响宽城地震台体应变仪的地下水位、温度、气压等相关因素进行了相关性分析,得出了宽城地震台体应变仪数据主要受到地下水位和气压的影响,温度则对宽城地震台体应变仪影响较小。通过观测数据拟合分析来看,宽城地震台体应变仪映震能力较好,体应变仪在震情监测预报以及地震研究工作起到重要的作用,对地震监测预报工作的长远发展做了较大的贡献。
Based on the volume strain data in Kuancheng seismic station,the dynamic characteristics of the well section（2005-2008）was analyzed.And according to the analyses of the groundwater level,the temperature,the atmospheric pressure,and some related factors of the volume strain instrument,it is found that the main effect factors are the ground water and the atmospheric pressure.And the temperature didn＇t affect much.By fitting analyzing the data of the volume strain,we found that the earthquake reflecting ability of the volume strain worked well.It played an important role,and would make outstanding contribution to the development of the earthquake monitoring and the prediction.
