【摘要】 在塘沽地震台与津滨轻轨之间及向北延长线建立野外磁测剖面,对轻轨运营期间的磁场干扰变化进行了实测研究,并对实测结果进行了曲线拟合,得出满足规划中的地磁观测网的环境要求——在以津滨轻轨铁路为骚扰源的影响范围,地磁观测网的地磁固定观测台距轻轨铁路的距离应大于24km。更多还原

【Abstract】 For experimental study the magnetic disturbance of the operation of light rail,a field magnetic profile between the Tanggu Seismic Station and the Jinbin light rail and its northward extend line is established. By fitted the survey results with curves,the environmental demand to satisfy the layout of geomagnetic observation network is obtained:in the affecting region of Jinbin light rail,the distance between the permanent station in geomagnetic observation network and the light rail must be larger than 24 km.更多还原
