A Numerical Study of the Screening Effectiveness of Open Trenches for High-Speed Train-Induced Vibration
Figure 11
Location-frequency figure with an open trench of = 10 m, = 1 m, and = 3 m (a) contour plot of displacement spectrum on ground surface and (b) surface plot of displacement spectrum on ground surface (Poisson’s ratio = 0.25, train speed = 180 km/h). Note: the location coordinate of trench is from 2.5 to 3.5 m.
