Dynamic Response Analysis of Underground Station Under the Action of Falling Ground Vibration

---

In recent years, because of the controlled blasting engineering in China concentrated in the downtown area, the surrounding environment of the downtown area is complex and the underground pipeline is dense, which poses a great challenge to the controlled blasting. It is of great significance to study the impact of falling ground vibration caused by controlled blasting on the underground station. Based on the numerical simulation analysis of ground contact vibration, the dynamic response of underground stations under the action of falling ground vibration is studied by using finite element software. Discuss the propagation rules of acceleration and velocity of ground surface of dynamic response caused by the collapsing touchdown vibration and the propagation law of the velocity, acceleration and displacement of the top and bottom plate of the underground station, and the research shows that: (1) In the area of 5–20 m from the collapse point, the vibration caused by the collapse is dominated by vertical vibration, and the vertical vibration decays faster; (2) The vibration of the roof and floor of the underground station is also dominated by vertical vibration, and the phase difference of vibration exists.
