The Practical Formula of Ground Vibration Attenuation Induced by the Parallel Vehicles on a Ring Road

Abstract:

In this paper, based on the transient moving load equivalent radius, multiple non-point source within as multiple small non-point source, ground vibration amplitude for multiple small non-point attenuation stack, on the basis of considering the ground more than car parallel, will vehicle load simplified as parallel concentrated load, according to the harmonic waves equivalent radius, considering different soil types of geometric attenuation coefficient, gives a practical formulas with ring road of ground vibration attenuation caused by parallel vehicles. And through the comparison between the Xi’an bell Tower ring road traffic vibration decays monitoring and calculation results, the practical formulas are verified.
