摘要
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。
This paper has dealt with the train-induced ground vibrations under a moving train. The solution method is to apply the 2.5D FEM that is based on the transversal FEM with the wavenumber expansion for response along the track. The validity of the method is verified by the mutli-layer method. Lastly, ground vibration induced by subway train load is analyzed by the method.
