Popis:	When using controlled blasting technology to demolish a building, the blasting vibration caused by the blasting process may harm the surrounding structure of the blasting area. To study the influence of blasting vibration on the adjacent subway structure, this paper takes the blasting demolition of a building in Chengdu as an example, analyzes the load during the blasting process, establishes the stratum-structure and load-structure finite element models of the subway structure, and simulates the dynamic response process of the structure, and then studies the safety impact of blasting demolition vibration on the adjacent subway structure. Studies have shown that: under the blasting construction scheme in this paper, the impact of blasting vibration on the subway structure is within a safe and controllable range.
