摘　　要：昆明地区在小江南北向地震带与易门南北向中强地震带之间,而小江断裂带是历史上多次发生7级以上地震的典型的强震带。以昆明市呈贡新区场址为例,分别用等效线性化法和递推算法对土层进行地震反应模拟,从而得到土层振幅的放大倍数。比较这两种算法的优缺点,针对性的提出优化意见。因此,本文的研究内容以及研究结果对昆明地区特别是呈贡新区的工程抗震有重要意义。Kunming area lies between north-south earthquake belt of Xiaojiang and north-south earthquake belt of Yimen. Among them, Xiaojiang fault zone is strong earthquake belt, in history, repeatedly earthquakes which are highly of seven have been happened here. Suitable to Chenggong new area in Kunming as an example, with the equivalent linearization method and recursion method to simulate the responsing of soil seismic, then the soil amplitude magnification is got. Comparing the advantages and disadvantages of the two algorithms, then the targeted optimization suggestions is proposed. Therefore, the research content and research results have important significance in Kunming region, especially in the Chenggong new area.
