| 摘 要： | 软土中隧道的纵向不均匀沉降是当前中外工程技术人员关心的热点,各种研究提出了引起不均匀沉降的多种原因。限于分析列车激扰对隧道纵向不均匀沉降的问题,用有限元方法对土与隧道系统的平面应变问题,进行了静动力学的数值分析,得到了系统的动力特性,比较了上海在建隧道现场实测的试验结果,比较了地铁列车的激扰频率,得出了动力学激扰引起的振陷是软土隧道沉降不容忽视的诱因。

| Abstract: | Nowadays,the longitudinal asymmetric sedimentation of tunnel in soft soil is the hot topic which is concerned by technologists including both Chinese and foreigners,different causations that bring the asymmetric sedimentation have been raised.Limited to the analyses of the longitudinal asymmetric sedimentation of tunnel caused by train, by utilizing the way of finite element,it is the model of mechanics of plane strain issue of linear elastic soft soil and tunnel system that is analyzed and compared numeric... |
