Abstract


With the rapid development of modern industry and the improvement of living standards of urban residents , the negative impact of the subway vibration has caused widespread concern and research environment that was caused by the vibration response is a very important issue . In this paper, the Shanghai Metro and along the ground vibration test and finite element computational analysis of metro vibration . In this paper, the Shanghai Metro Line and 2 along the line of ground vibration testing venue vibration time domain and frequency domain characteristics analysis , comparison of the vibration characteristics of the train in the run of the ground segment and Buried Section , analysis of the train the distribution characteristics of the regularity and frequency of vibration propagation in the case on the downhill , and combined with a variety of vibration control the standard venue vibration evaluation . Then use a general purpose finite element software , combined with the load data from the test results , to simulate the vibration response of the subway , the calculation and analysis of the vibration wave in the propagation of surface and qualitative discussion of vibration transmission tunnel depth . Finally, the analysis of the presence mainly due to differences in the calculation results and the test data .
