摘　　要：将现行的地震地电场前兆地表水平方向观测方法改为深井电极垂向地电场观测方法,可大大缩小观测场地范围,有效排除地表电磁环境的干扰影响,解决目前地电场观测场地选择困难、干扰影响严重的问题,更好地获得地震前兆信息。开展深井电极垂向地电场观测,可充分利用深井钻孔的条件,安装其他项目观测装置,开展综合观测,取得更丰富的观测资料。利用已有台站的深井钢管作电极,开展地电场前兆观测,可等同于深井电极垂向地电场观测,开辟地震前兆观测新途径,具有较好的观测效果;实现在老台站增设地电场观测项目而不需要太大的投资,值得推广。The replacement of seismic geoelectric field precursor observation method of the current horizontal direction on surface to vertical direction of the deep well electrode can greatly reduce the range of the observation site and effectively eliminate the interference effect of the surface electromagnetic environment.This change solves the problem of difficult site selection and serious interference effects in the geoelectric field observation,and gets better earthquake precursor information.Other observation devices can also be installed in the deep well and carried out comprehensive observation.More abundant observation data will be more conducive to the development of earthquake prediction.Using the existing deep well steel tube as electrode,the observation effect of geoelectric field precursor is good and can be equivalent to the deep well electrode vertical observation.An additional geoelectric field observation project on the basis of the old station doesn＇t need to invest too much,so it is worth promoting.
