摘　　要：随着城际轨道交通的迅速发展,列车营运引起的环境振动造成人体的不舒适已成为人们关注的焦点之一.通过对隶属度和振动加速度之间的关系的分析,建立了基于模糊理论的建筑结构内人体舒适度的烦恼率模型.利用隧道——建筑物三维有限元结构模型,并采用车辆轨道系统随机振动荷载时程谱加载,模拟得到了地铁车辆振动引起的建筑物内各层楼板中心点的加速度、速度等振动参数,给出了地铁振动引起的烦恼率曲线,进而得到了地铁列车运营产生的振动相对于人体舒适度参数.With the rapid development of inter-city rail transportation, people have paid more attention to the comfortlessness caused by environmental vibration during the train operating. By analyzing the relationship between membership degree and vibration acceleration, an annoyance rate model for human body comfort degree in buildings was proposed based on the fuzzy theory. Tunnel-building finite element model was set up and the time--history loads were uti- lized to analyze the effect of acceleratory parameters on the center of the each floor. The annoyance rate curve and human body comfort parameters generated by subway operation vibrations were obtained.
