摘　　要：目前,关于危险参数设计下地铁运行对于古城墙的振动影响还缺乏定量研究。论文利用ABAQUS建立整体模型,计算地铁单次经过时,危险条件设计下隧道埋深、列车载重以及行驶速度3种参数对古城墙的振动影响,并考虑减振措施产生的效果。其结果揭示了上述3种参数危险设计时的不利影响,结合振动限值研究,提出古城墙保护建议。At present,there is a lack of quantitative research on the vibration influence of subway operation on the ancient city wall under the dangerous parameter design.The paper uses ABAQUS to establish an overall model,calculate the influence of tunnel buried depth,train load and running speed on the vibration of the ancient city wall during the single passage of subway,and considers the effect of vibration reduction measures.The results reveal the adverse effects of the above three parameters in danger design,and combined with the vibration limit study,the protection of the ancient city wall.
