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。
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 earth- quake 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 meth- ods, 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.
