Study on the Vibration of Geosynthetic Reinforced Cushion in Pile Supported Embankment
Abstract The vibration of geosynthetic-reinforced cushion in pile supported embankment due to high-speed train load is theoretically investigated in this paper. The cushion is considered as an elastic sheet on viscoelastic foundation. The high-speed train load is assumed as a dynamic load made up of a stationary load and three sinusoidal loads. An analytical solution of the vibration response of cushion due to high-speed train load is obtained. Numerical examples are given to analyze the vibration characteristics of cushion and the effect of the train speed, Young’s modulus and thickness of cushion on the displacement response. The results show that the displacement response of cushion increases as the train speed increases. The peak value of displacement increase steeply with the decrease of damping. Furthermore, the influence of high-frequency load on the displacement decreases with the increase of the train load and damping. Properly increasing the Young’s modulus and thickness of cushion can effectively reduce the displacement of cushion.
