宝鸡地震台地电阻率观测效能评价
|
摘要
根据中国地震局电磁学科技术管理组制定的《地电台站观测效能评估方案》,对宝鸡台地电阻率观测效能进行全面评价。从评价结果来看,宝鸡地震台地电阻率的台址结构条件、电磁环境、台站观测系统等均符合地电阻率台站建设规范要求;地电阻率观测精度不低于3‰测值,保证了准确测量不低于1%地电阻率异常的指标需求。宝鸡地震台地电阻率对本区及附近地区中等以上地震有一定监测能力,其观测数据在本区及附近地区地震监测、预报和地震科学研究及相关科学研究中有重要价值。
The observation efficiency of the earth-resistivity of Baoji Seismic Station has been evaluated comprehensively according to The Observation Efficiency Assessment Plan of the Geoelectric Stations by China Earthquake Administration (CEA). We may see that such assessment results of the earth-resistivity in Baoji Seismic Station as the site foundation,electric-magnetic environment and observation system meet the technical demands for building a station. Meanwhile,the observation precision of 3‰ ensures to measure accurately the abnormal geo-resistivity of not less than 1% in this station. The data of the geo-resistivity in Baoji Station play an important role in the seismic monitoring,earthquake prediction and scientific research of the mid-or large-scaled earthquakes in the local and neighboring regions.
