STUDY ON ELECTRICAL STRUCTURAL CHARACTERISTIC PARAMETERS OF MEDIA UNDER GROUND RESISTIVITY STATION FOR EARTHQUAKE PREDICTION

以地下浅部水平层状介质模型为基础，依据电测深资料，计算研究了表征台址电性结构具有抑制干扰能力和映震能力的特征参数：干扰系数α、γ和异常系数β及其物理特性和应用。综合研究结果表明，特征参数比电测深曲线和电性参数更直观、定量地表征台址电性条件的优劣，应用更广泛。

Based on the model of horizontal layered media under ground and relevent electrical sounding data,the characteristic parameters such as disturbance coefficients (a,Y) and abnormal coefficient(5)which can represent the electrical structure of the media under station andhave ability of restraining disturbance and reflecting earthquake are calculated, and theirphysical characteristics and application in earthquake prediction are also studied in this paper.The results of comprehensive research show that the parameters mentioned above are more objective than electrical sounding curves and electrical parameters and have advantages of quantitatively representing the electrical condition of station and having more extensive application.
