Subway car depot testing line composite vibration-isolation barrier
The invention discloses a subway car depot testing line composite vibration-isolation barrier. The composite vibration-isolation barrier is arranged in a foundation soil layer under the two sides of a testing line railway ballast. The overall depth D, the overall width W and the distance S between the vertical face, close to the railway ballast, of the inner side of the vibration-isolation barrier and the vertical face where the center line of a testing line rail is located meet the following conditions that D is larger than or equal to 0.5 lambda R, W is larger than or equal to 0.1 lambda R, lambda R is larger than S, and S is larger than or equal to 0.7 lambda R, wherein lambda R is the Rayleigh wavelength of first-layer foundation soil at the bottom of the testing line railway ballast. The vibration-isolation barrier can effectively reduce vibration damage of subway car depot testing line rain operation to a superstructure, and thus reduces influences of vibration of a testing line train on the superstructure.
