【摘要】 为保证三河电厂的建设以及地震监测预报工作的持续进行，开展了马起乏测点迁移优化工作。按照测点迁移原则与实施技术方案，收集整理了三河及其附近地区的地质构造、地震活动性、航磁、地球物理等方面的基本资料。在马起乏周围１０－１５ｋｍ范围内进行了野外实地考察与勘测工作。经过分析比较，确定田庄、灵山、东兴在为合适的测点迁移的新地址。更多还原

【Abstract】 In order to ensure the construction of the Sanhe electrical power factory and to continuethe work of monitoring and predicting earthquake,the moving and optimizing the geo-magnetic sites around Maqifa was done.According to the principle and technical pro-gram of moving the site,we collected and sorted out the basic data about geologicalstructure,seismic activity,aeromagnetic detection and geophysics in the Sanhe area andits neighbourhood. The field investigation and survey were carried out in the extent of10─15 km around Maqifa.Through the comprehensive analysis and comparison,thenew sites at the Tianzhuang,Lingshan and Dongxingzhuang were determined as properones for moving sites.The environment around the sites is good,and there is no anyelectromagnetic disturbance,The marble survey stakes with no magnetism,as the per-manent mark of the site for a long time, were buried at the main and subsidiary points ofeach site.These sites all agree with the regulation of the geomagnetic survey.更多还原
