The Study on the Influence of Vibration on the Existing Subway Induced by New Mass Transit Railway
|Title||The Study on the Influence of Vibration on the Existing Subway Induced by New Mass Transit Railway|
With economic development and urbanization, it is an increasing demand for transport, urban transport systems in large-scale trending with great speed. A large number of metro, suburban railways and the construction of light rail greatly facilitate people’s travel; the transfer between the different lines is also very convenient. For facilitating the cities among the different train station transfer traffic, and alleviating the traffic pressure on urban areas underground diameter line were built to connection among the different train station in recent years, improving the rail hub cloth. Because of its density and the original axle load and operate the different subway lines, Diameter line’s operation would give rise to a new environment after the vibration problem, right around the surface, the existing subway structure, adjacent buildings and other adverse environmental impact, and then superimposed caused by the operation on a subway train vibration, impact on the surrounding environment will be more prominent. To address this outstanding issue, it is necessary to train the vibration caused by the spread of, and control research, buildings and underground trains to ensure the normal use and operation.In this paper, the establishment of the train-track system coupling dynamic model, by solving the system vibration equation using MATLAB, respectively, simulate the diameter line trains and subway train passing through the vibration time-curve; through the establishment of three-dimensional tunnel model by ANSYS analysis the influence of the impact and vibration of the diameter line lonely and diameter line and Subway work together.
