摘要
新建赤峰至京沈高铁喀左站铁路区间朝阳沟隧道拟下穿燕内长城遗址结构,因此对全国重点文物保护单位燕内长城进行运营期间列车振动荷载影响研究十分必要。采用有限元分析软件ANSYS,将列车动荷载作为激励作用于动力有限元模型上,通过数值模拟计算,预测评估高铁列车荷载对燕内长城的振动响应。并通过查阅国内外相关振动控制标准,最终提出该文物的容许振动速度限值。结果表明:在动力加载作用下,燕内长城速度波动范围小于容许限值,即高铁运营振动对燕长城遗址结构的影响较小。
The Chifeng to Kazuo railway station of Beijing Shenyang high-speed rail tunnel is planned to cross the quasi Chaoyang in the Yan Great Wall,it is necessary to study the effect of train vibration load during the operation on the Yan Great Wall which is one of the national key cultural relics protection units.In this paper,the finite element analysis software ANSYS is used to train the dynamic load as an incentive to the dynamic finite element model.By numerical simulation,the vibration response of the high speed railway train load is predicted and evaluated.By referring to the domestic and foreign relevant vibration control standards,the allowable vibration speed limit of this cultural relic is finally put forward.The results show that under the action of dynamic loading,the speed fluctuation range of the Yan Great Wall is smaller than the allowable limit value,that is,the high speed rail operation vibration has little influence on the structure of the Yan Great Wall ruins.
