Experimental Study and Numerical Analysis of Sihui Metro Depot and the Superstructure
Field tests were carried out on Sihui metro depot of Beijing metro line 1 and its superstructure.The acceleration time history of sleepers and floors of the building was obtained, and the waves-propagation laws of building were studied through the tests.Test analysis shows that the structure vibrations show zigzag tendencies ascends with the height of the building.Based on current situation of Sihui metro depot, a metro-soil-building 3-dimensional finite element model is established on ANSYS.By using actual acceleration of sleepers as inputs, the dynamic responds rule of the superstructure is obtained.Compared calculation results with the experimental results, the given numerical model can predict the vibrations of the building induced by moving trains quite well.This method can provide guidance and technical support for future development of superstructure.
