电气化铁路对平凉地震地电观测干扰的实验研究

EXPERIMENTAL RESEARCH ON THE GEOELECTRICTY OBSERVATION DISTURBANCE CAUSED BY THE ELECTRIC RAILWAY AT PINGLIANG GEOELECTRIC STATION

详细介绍了宝中电气化铁路通车前后，平凉地电台自然电场及地电阻率的实测试验。结果表明，电气化机车通过平凉地电台测区时，产生强烈的交流干扰，致使自然电场和地电阻率观测无法正常进行。

The observational experiments of natural telluic field and earth resistivity atPingliang station have been conducted before and after the opening of Baozhong electricrailway. The related situation is introduced in detail in this paper. The experimental re-sults indicate that when electric locomotives pass through the observational area ofPingliang station, extensive disturbance of alternating current caused, which resuled infailure of the normal observation at the station.
