Research purposes:The planned Shanghai-Nantong Railway will pass through the Shanghai Waigaoqiao Free Trade Zone on viaduct and it will be about 250 m away from a chip processing plant.In order to ensure the normal production of the chip processing factory,it is necessary to test and analyze the vibration induced by the elevated railway and present the anti-vibration measures according to the test results. Research conclusions:The vibration value of the place around the chip processing factory has exceeded the allowable vibration velocity for the foundation of the chip processing workshop because of the vibration induced by the container truck on the peripheral road.The similar vibration tests and monitoring for the existing Shanghai-Hangzhou Railway showed the vibration value of the ground 250 m away from the track was equivalent to the that of the chip processing factory when the passenger train met with the freight train and it exceeded the allowable vibration velocity.On consideration of that the building was built in the place about 500 m away from the railway,the study mainly demonstrated how to reduce the vibration level of the place 250 m far away from the railway to being equivalent to that of the place 500 m far away from railway.The study showed the anti-vibration measures were feasible.
