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。 The observation of apparent resistivity in buried metal pipelines is detrimental. Resulting in a substantial change in observations, beating, no law to follow. In severe cases, even the station was scrapped and was forced to relocate. Inspired by some emergencies, combined with field experiments and citing some theoretical calculations, the author explored how to basically overcome the interference of observations by simply making minor modifications to metal pipes. The method has been effective for more than six months in Hongtai test. Observations restored to the previous level of water pipes installed, no significant beating. The method saves money, is simple and easy, greatly improves the survivability of a station in a complex environment.
