| Abstract: | Based on relevant electrical sounding data, the electrical structural characteristic parame- ters such as disturbance coefficients（α,γ） and abnormal coefficient（β） are calculated accord- ing to the data of 3 geo-resistivity stations of Hefei, Feidong and Mengcheng. The change rates of characteristic parameters and the proportional relations among them are discussed on different electrical structural, different electrode distance and different measuring direction. The results of correlation research show that the parameters can intuitively represent the capability of restraining disturbance and reflecting earthquake of the stations under different electrode distance. The results are significant for guiding the precursor abnormity judgement. |
