Abstract

It is well known that in general the underground railways always cause urban environmental vibration. Therefore, the more the underground railways which were built or under construction, the more serious the environmental vibration is. It is difficult to estimate to what degree the vibration, which was generated in the ground propagation by subway, attenuated with distance. At present, no practical method is available to calculate the ground vibration in current engineering by theory of wave. The effect of geometric damping、elastic wave theory in soil、material damping、equivalent radius of wave source of subway、the frequency of tunnel structure、source, which interacted around the soil medium, embedded depth、superimposed surface wave on wave propagation were presented in this paper. A practical equation for calculation of ground vibration propagation induced by underground railway is presented in the paper. The prediction value of vibration with the distance using the equation in this paper approximately complies with the field test results.

Urban Environmental Vibration Induced by Underground Railway

New York, New York

It is well known that in general the underground railways always cause urban environmental vibration. Therefore, the more the underground railways which were built or under construction, the more serious the environmental vibration is. It is difficult to estimate to what degree the vibration, which was generated in the ground propagation by subway, attenuated with distance. At present, no practical method is available to calculate the ground vibration in current engineering by theory of wave. The effect of geometric damping、elastic wave theory in soil、material damping、equivalent radius of wave source of subway、the frequency of tunnel structure、source, which interacted around the soil medium, embedded depth、superimposed surface wave on wave propagation were presented in this paper. A practical equation for calculation of ground vibration propagation induced by underground railway is presented in the paper. The prediction value of vibration with the distance using the equation in this paper approximately complies with the field test results.
