【摘要】 测震作为地震监测的主要手段,在地震的监测预测中有着非常重要的作用。为满足测震需要,无人值守遥测地震台站建设不断增多。然而,测震台台基的选择和避雷接地电阻的要求是一对矛盾。台基好电阻率一般较高,要达到较低的接地电阻很难,涉及的经费开支也较大。本文应用雷害风险评估方法,讨论遥测地震台站防雷问题,提出因地制宜限制投资的防雷设想。更多还原

【Abstract】 As the main means of the earthquake monitoring,digital seismograph techniques play an important role in the earthquake monitoring and forecasting.To meet the needs of the earthquake monitoring,unmanned telemetry seismic stations have been increased.However,the claim of station site selection and grounding resistance for lightning-proof is contradictory. The better the bedrock of station is,the higher its resistivity is.The expenditure is high to attain a low grounding resistance.In this paper,using the lightning risk assessment methods, the lightning-proof telemetry of telemetric seismic station is discussed.According to adjust measures to local conditions,the method for lowering the lightning-proof investment is proposed.更多还原
