Abstract
With the development of urban rail transit, environmental vibration caused by the operation of rail transit vehicles has increasingly attracted people's attention. This article introduces the evaluation method of the influence of vehicle operation on the residents, building structure and mechanical equipment in the rail transit environment. The calculation methods and calculation parameters of the evaluation index quantity is analyzed and discussed. The trend of influence of different calculation parameters on the calculation results is obtained. The results show that increase of the number of analysis points will reduce the calculation result of the maximum vibration level in the frequency division. The value of the peak retention method is larger than that of the linear average method. After the overlap coefficient is greater than 3/4, the calculation result will tend to be stable. This article provides a reference for accurately evaluating the environmental vibration levels of rail transit.关键词
