Adopting this model, we analyze the seismic hazard near the Chelungpu fault that generated the Chi-Chi (Jiji) earthquake with magnitude 7.6 and the following conclusions are reached. ①This model is reasonable on the base of focal mechanism, especially for

结果表明：①采用潜在地震破裂面源模型是合理的，因为它可以模拟地震破裂面与地震动影响场的三维展布特征，尤其适用于较大震级地震的近场区域；②潜在地震破裂面源的大小、产状，对近震源场点的地震危险性分析和地震区划结果有明显的控制影响。
