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。 The Kunming area is between the Xiaojiang North-South seismic belt and the Yimen South-Northward-Middle Earthquake Belt, while the Xiaojiang River fault zone is a typical strong earthquake zone with many earthquakes of magnitude 7 or higher in history. Taking the site of Chenggong New District in Kunming as an example, the seismic responses of the soil layer are simulated by the equivalent linearization method and the recursive algorithm, respectively, to obtain the magnification of the soil amplitude. Comparison of the advantages and disadvantages of these two algorithms, targeted optimization suggestions. Therefore, the research contents of this paper and the research results are of great significance to the seismic engineering of Kunming area, especially Chenggong New Area.
