摘要
随着我国经济建设的发展,一些地电台站的观测环境受到大面积施工破坏形成大面积干扰源,给地电观测带来干扰。文中对地电台站观测环境干扰源的影响作了一定的理论推导,对其引起的干扰电位进行了计算;同时对干扰电位与观测电流关系、环境保护距离等进行了探讨。
With the development of Chinese economy, the observational evironment of some geoelectricity stations were ruined due to projets construction in large scale areas. The resistivity observation are interferenced.
In this paper, the interfering voltage which caused by large scale in terference source are cacylated. The relation between interfering voltage and measurment cullent, the environment protecting distance are discussed.
