Anomaly analysis of earth resistivity in NS direction at Datong Seismic Station
摘要
Abstract
The annual aberration of resistivity from Datong Seismic Station in NS direction is detected since 2014.After investigation,we found that the surrounding environment changes with barbed wire.Based on the electrical sounding data of earth resistivity of NS direction,the electrical structure of the measuring region are inversed on horizontal layered model.The sensitivity coefficient of each layer medium in under NS direction is calculated.Annual variation of"Low in summer and high in winter" of each resistivity is interpreted.On the base,we qualitatively analyze the disturbing effects caused by the barbed wire using numerical analysis three dimensional sensitivity coefficient.The result show that the change isn't anomaly.关键词
