In order to provide quantitative reference for avoiding interference sources such as pump,train station and quarry blasting in strong motion station establishing and station environmental protection work,some tests on site are done and the vibration attenuation relationships of these three interference sources are discussed.The studies suggest that the distance from the station for early warning and fixed observation to pump should be more than 69 m,to train line（low-speed for passenger and freight） should be more than 228 m,and to quarry should be more than 723 m.The distance from the station for quick report to pump should be more than 19 m,to train line should be more than 156 m,and to quarry should be 428 m.
