Influence Of High Speed Railway Train Vibration On The Environment And The Solution

In recent years,the laying and research of high speed railways has been developing rapidly in China.At present,most cities in China have high-speed railways,which greatly facilitates people's life and drives the development of economy.At the same time,the impact of high-speed rail's vibration on the surrounding environment can't be ignored,especially for the research institutes with special precision instruments.In this paper,through the analysis of the actual situation of Shijiazhuang high speed railway section,using MIDAS finite element analysis software to establish the road soil building three-dimensional finite element simulation model,dynamic effect between geology and high speed railway vehicles,rail,experimental building comprehensive consideration,analyzed the influence of vibration of high-speed railway train of a university physics experiment along the floor,and rational planning of the appropriate mitigation measures.The main research results are as follows:(1)According to the data collected,relevant finite element models has been established.By selecting suitable pickup points,the article analyze the vibration response rules of high speed rail vehicles during the operation process,and summarize the horizontal and vertical vibration responses of the soil.(2)By changing the train parameters,the rule of train vibration propagation under different traffic conditions and the impact on the vibration of the laboratory building can be understood.In the running state,the propagation law of soil vibration and the influence on the vibration of the experimental building at different speeds are analyzed.(3)Through the analysis of the vibration response of the foundation of the experimental building,the effect of vibration isolation measures is calculated,and the influence of the related parameters of the vibration isolation trench is analyzed.
