轨道交通振动对邻近建筑物的影响及其评价
|
摘要
发展城市轨道交通是解决城市交通问题的有效措施,所产生的振动和噪声形成环境问题,成为发展的"瓶颈"。文中以北京城轨道交通13号线霍营-回龙观段的观测振动信号作为输入,选择6层、10层和16层钢筋混凝土结构以及5层砌体结构,建立土结相互作用三维有限元模型,计算结构各层振动响应以及傅氏谱,从这两方面分析结构响应随距离的变化关系。最后计算结构各层振动加速度级,用中国和ISO环境振动标准对计算结果进行了评价,为解决城市轨道交通系统问题提供相应的技术支撑。
Developing rail traffic is an effective countermeasure to solve the traffic problems in China,but the environmental problem due to vibration and noise from the traffic turns into a bottleneck in the development of urban areas.Considering the vibration signal obtained from the 13th line of Beijing urban rail traffic as an input for four kinds of structures,such as six-storey,ten-storey and sixteen-storey reinforced concrete and five-storey masonry,the responses and Fourier spectra of all the storeys were calculated.And then the relationship between structural responses and distance was also summarized.In the end,vibration acceleration levels of the structures were calculated.The results of environmental vibration were evaluated with China and ISO standards.The results provide appropriate technical support for solving the problems of urban rail transit system.
