以国家地震重点防御地区的调查结果为基础，基于近场强地震动预测方法体系进行了昆明普渡河一西山断裂设定地震（M6．5）的强地震场预测研究．预测方法采用三维有限差分元法和改良的统计学格林函数法组合的复合方法．针对昆明盆地三维地下结构模型和基于昆明活断层探测和危险性评价结果的特征凹凸体震源模型进行了计算．结果表明盆地构造对于盆地边缘附近地区的强地震动波形的振幅具有显著的影响作用，复合预测方法可以模拟盆地产生的面波在内的宽频带强地震动场，为基于考虑区域环境条件的近断层强地震动场基础上的城市和重要工程的地震评价提供了可能．

英文摘要：

On the basis of the project of Kunming Active Faults and Seismic Hazard Assessment, strong ground motion in the Puduhe-Xishan earthquakes （M6.5） was predicated by the hybrid method, three-dimensional finite difference method （3DFDM） and stochastic Greenrs function （SGF）. 3D structures of the Kunming sedimentary basin and the characterized asperity model describing source heterogeneity of the strong motion were simulated. The results indicate that the sedimentary deposits of the basin signi cantly affect the ampli cation of simulated ground motion near the basin edge and that this effect depends on the direction of wave incidence. Results demonstrate the practical simulation of wave propagation including basin induced surface waves provide a possibility for valuating the important engineering structure basing strong ground motions near-fault considered local geological conditions.
