摘要通过开展地裂缝场地振动台模型试验，研究西安地裂缝场地动力响应规律及场地抗震设防问题。试验结果表明：越靠近地裂缝峰值加速度越大，随着距地裂缝距离逐渐增加，地表峰值加速度逐渐减小后趋于稳定，其影响范围为上盘约30 m，下盘约18 m；随着输入地震动强度逐渐增大，地表峰值加速度逐渐增大但增幅不同；受地裂缝的影响，地裂缝场地动力响应表现出明显的“上盘效应”及“分带性”规律，具体可划分为“避让带”、“设防带”及“安全带”；随输入加速度峰值的增大，场地地震放大效应呈整体减小趋势，这种变化趋势在激励加速度峰值为0.3 g时出现拐点后变化趋于稳定。模型试验结果为西安地裂缝场地工程抗震设防提供了理论依据。

Abstract：The response of Xi?an ground fissure site and its site seismic design were studied by conducting a shaking table model test. According to the test results，the closer of the ground fissure，the greater of the peak acceleration，with the increased of ground fissure distance，the peak ground acceleration gradually decreased and stabilized gradually，and the range of influence was about 30 m in the hanging wall，while 18m in the footwall；with the increased of input ground motion intensity，the peak ground acceleration gradually decreased but at a different rate；the dynamic response of the ground fissure site shows obvious “hanging effect” and “zoning” laws affected by ground fissures，which can be divided into “Yield belts”，“defensive belts” and “safety belts”type；with the increased of input ground motion intensity，the site seismic amplification decreased integrally，which is tend to stabilized when the peak acceleration reached 0.3 g. The model test results provide a theoretical basis for the seismic fortification of the ground fissure site engineering in Xi′an.
