摘要
根据已有的研究成果 ,建立了丽江主震的地震破裂模型。利用在两个场点上记录到的丽江地震最大余震M6 0的加速度 ,用经验Green函数法合成了主震在这两个场点上的加速度时程 ,计算了相应的反应谱 ,分析了地震破裂过程对震害的影响 ,发现两个场点的合成结果与地震所造成的宏观破坏现象是一致的。
Based on the previous study results,a fracture model of Lijiang earthquake has been built up.The acceleration time history of main shock at two sites are synthesized and the response spectra are calculated by using the empirical Green function method and the acceleration records at two sites of the largest aftershock (M S=6.0) of Lijiang Earthquake.According to those results,the affects of the earthquake broken process to the disaster is discussed.The results are identical with the macro-damage phenomena caused by the earthquake.
