Reduction of train-induced vibrations on adjacent buildings

Abstract     [Buy Article]
    In this paper, the procedure for deriving an infinite element that is compatible with the
quadrilateral Q8 element is first summarized. Enhanced by a self mesh-expansion procedure for generating
the impedance matrices of different frequencies for the region extending to infinity, the infinite element is
used to simulate the far field of the soil-structure system. The structure considered here is of the box type
and the soils are either homogeneous or resting on a bedrock. Using the finite/infinite element approach, a
parametric study is conducted to investigate the effect of open and in-filled trenches in reducing the
structural vibration caused by a train passing nearby, which is simulated as a harmonic line load. The key
parameters that dominate the performance of wave barriers in reducing the structural vibrations are
identified. The results presented herein serve as a useful guideline for the design of open and in-filled
trenches concerning wave reduction.
 
Key Words
