地铁列车运行引起的环境振动评价
|
摘要
随着城市地铁建设的快速发展,地铁运行引起的环境振动问题引起了社会的广泛关注。以软件ABAQUS为计算平台,给出了模拟地铁列车振动荷载的表达式;采用修正Martin-Seed-Davidenkov动粘弹塑性本构模型描述土的动力特性;分析了地铁列车运行引起的地表振动特性;以地表振动加速度振级表征地表振动强度,对地表振动强度进行了分析和评价,为地铁线路选线和地铁沿线邻近建(构)筑物的减隔振设计提供一定的依据。
With the fast development of the urban subway construction in China,the environmental vibration problem induced by passing trains in subway tunnel has aroused broad attentions of the society.The soil dynamic viscous-elastic-plastic constitutive model based on the Davidenkov model was used to describe the dynamic character of soils.The equation describing the vibration load induced by passing trains in subway tunnel was given and the characters of ground vibration induced by passing trains in subway tunnel were analyzed.The grade of ground surface vibration acceleration was used to describe the intensity of ground surface vibration,and the intensity of ground surface vibration induced by passing trains in subway tunnel was evaluated.The results can provide some basic data for the choice of subway tunnel line and mitigation of environmental vibration.
