【摘要】 本文根据断层岩性、倾角、破碎带宽度和隐伏断裂上部覆盖层厚度等因素的变化，密切结合断层及其附近的地形地貌、上层剖面以及基岩面的起伏变化特点建立断层场地模型，并以合成人工地震动作为输入，对这些模型进行了二维地震分析计算，给出了各模型输出点地震动时程和反应谱．对计算结果进行了综合对比分析，取得了若干认识。此外，用宏观震害经验检验了本文方法的可行性和计算结果的可靠性。更多还原

【Abstract】 The models of near-fault site are established by considering the factors, such as fault dip. width of fault trace, thickness of covering layer on concealed fault. In addition, other factors, such as topographic feature near fault and bedrock relief etc., are also taken into account. After inputting the artifical seismic wave, the site effect and earthquake response of soil layers are analyzed by 2-dimensional wave motion model and the ground motion history and response spectrum of soil sites are given. After checking the different models and comparing with the history earthquake damage. the results are proved to be valid, reliable and helpful for aseismic design.更多还原
