| 摘 要： | 应用小震调制比法对山西地区１９７０年—１９９１年间发生的中强震进行了总结，表明山西地区５级左右地震在发震前４ａ～５ａ出现ＲＳ（小震调制比异常频次）双区异常，６级地震前１０ａ出现双区异常，中强震在震前３ａ左右Ｓｒｍ（小震调制比异常面积）呈现等周期起伏加剧现象，周期为１ａ。

| Abstract: | The paper gives the results of dynamic behaviors and the mean values of volume weight of the 8 types of soil (clay,subclay,clayey sand,powdery soil,silt,close sand,fair solidity sand and light sand)in Taiyuan area using the results of dynamic triaxial test of the 142 soil samples in Taiyuan area,the results can provide a reference for the model parameter defining of the earthquake safety appraisal work of buiding site in Taiyuan area |
