研究列车移动荷载作用引起的地基振动。采用2.5维有限元的方法,即通过沿轨道方向的波数扩展,在垂直轨道方向的平面上将地基进行有限单元离散。为了验证此方法的正确性,将其与分层法进行了比较。同时分析了地下铁路振动传播的规律。
Research on Ground Vibration Caused by Train Moving Loads. A 2.5-D finite element method is used to discretize the foundations in the plane of the vertical orbit by means of wave number expansion along the orbital direction. In order to verify the correctness of this method, it is compared with the stratification method. At the same time, the law of vibration propagation of subway is analyzed.
