| 摘 要： | 埋地金属管线对视电阻率的观测危害甚大。造成观测值大幅改变，跳动，无规律可循。严重时，甚至台站报废，被迫搬迁。通过一些突发事件的启发，结合现场实验，并引证了一些理论计算，笔者摸索出了只须对金属管道作局部微小的改造，就能基本克服其对观测的干扰的方法。该方法在红格台试验半年多来，取得了明显的效果。观测值恢复到安装的水管以前的水平，再无大幅度的跳动。该方法节约经费，简单易行，大大提高了台站在复杂环境中的生存能力。

| Abstract: | Buried metal pipe around a seismic station makes a great inconvenience to the observation of apparent resistance and causes the big fluctuation and irregular changes to the observing data.All inconvenience factors make the apparent resistance observation data useless.The station has to be moved to a new place.To solve this problem,some theoretical computation is made.The interference can be reduced by changing overall arrangement of the metal pipes.This method had been applied in Hongge Seismic Station for six months.Through some incidents and on-spot experiment,we had made an obvious achievement.The observation condition has been restored to the previous level before the pipe was installed.This method is economical and easy to carry out and greatly improves the station's adaptation in a complicated environment.However,there are still some theoretic problems to solve. |
