The urban shallow buried tunneling method is often used in the construction of civil air defense underground commercial streets and crossing passages in prosperous urban areas. The roof of this kind of project is generally relatively shallow from the ground surface, and the vibration caused by the driving of the car on the road will have a greater impact on the shallow buried and underground excavation construction. Numerical simulation based on ANSYS qualitatively analyzes the propagation law of vehicle vibration in the horizontal and vertical directions of civil air defense project, the vibration parameter of the shallow-buried underground excavation project of Shachang South Road in Luoyang City were tested, the horizontal and vertical acceleration of reinforced concrete structures under the road were obtained. The results show that in the horizontal direction, the acceleration value gradually decreases from the mid-span to the sides. In the horizontal direction, from top to bottom, the acceleration value decreases linearly. The acceleration value of vehicle passing is 1.48~5.33 times of that no vehicle, the adverse effects of road vehicles on the construction of shallow buried and underground excavation are obvious.
