摘　　要：本文依据现阶段地震动模拟方法,阐述了基于工程理论的地震动模拟方法。通过比较不同模型存在的优缺点并且结合实际地震动记录,说明了三角级数法仍是现阶段的普遍方法,研究了相位谱中存在的问题,总结相位差谱分布模型,并提出未来研究的方向。Based on the current ground vibration simulation methods, this paper describes the ground vibration simulation methods based on engineering theories. By comparing the advantages and disadvantages of different models and combining them with actual ground shaking records, it is shown that the trigonometric method is still the common method at this stage, the problems in the phase spectrum are studied, the phase difference spectrum distribution model is summarized, and the direction of future research is proposed.
