摘      要：A large model box was developed in our experiment to study the vibration reduction *** hydraulic highperformance actuators are arranged in the upper part of the model *** is a time difference between adjacent actuators,which can simulate the train induced *** reduce vibration a composite barrier is designed;the barrier consists of a honeycomb concrete canvas and PE polymer water *** concrete canvas can be mixed with water to produce a hydration reaction to form a structure with a certain *** simulating different train speeds and loads,vertical vibration velocity,and acceleration before and after the barrier are compared and *** experimental results show that the new barrier can achieve a good vibration reduction *** the simulated train speed increases,the damping effect of the barrier is *** a speed of 180 km/h,an amplitude of 1.5 m after the barrier is found to be 48.6%lower than that before the *** decreases by 24.2%at 36 km/h and by 38.1%at 108 km/h.
