本文着重分析讨论了甘肃省内十五个地电台站的岩性条件、覆盖层岩性及厚度的影响、水文地质条件及电性条件,並从物理机制上对温度给予电阻率的影响进行了粗浅的分析,认为用电测深法定期监测震源深度的电阻率变化反应震源区地温度化是予报地震的有效手段。在地电研究室其他同志的配合下作者对省内大多数台站作了垂向电测深工作,並着重对嘉峪关台老布极区作了电测剖面,解释了该台原布极道电阻率年变化与地下水形态成反常关系的原因。作为对上述讨论的台址条件的检验与印证,文章对历年来在地电台站附近发生的258个地震与电阻率异常对应关系作了统计和分析。並综合评述了省内地电台站台址条件的优劣状态。
This paper analyzes and discusses the lithology conditions, lithology and thickness of overburden, hydrogeological conditions and electrical conditions of 15 ground stations in Gansu Province. The physical mechanism is also given to the influence of temperature on the resistivity The superficial analysis shows that it is an effective measure to report earthquakes by observing the resistivity changes of the source depth by electrical sounding method. In cooperation with other colleagues of the Geoelectric Power Research Office, the author made a vertical electric sounding survey on most of the stations in the province and made an electrical and electrical survey of the Laodobu area of Jiayuguan station, explaining the original resistivity The reasons for the anomalous relationship between the annual change and the groundwater form. As a test and confirmation of the above-mentioned site conditions, the article has calculated and analyzed 258 anomalous correspondences between earthquakes and resistivities occurring in the vicinity of the earth stations over the years. And comprehensively reviews the advantages and disadvantages of the station’s site conditions in the province.
