| Abstract: | Blasting construction is needed in the tunnel excavation,and it will affect the adjacent structures.The data on the blasting vibration observation of a railway tunnel are analyzed.And based on the main blasting vibration safety criteria in our country,the safety influence circles of the blasting construction to buildings are discussed,and the safety of the adjacent buildings is evaluated.Combined with the cracks of the adjacent buildings,the probable damage caused by blasting vibration are analyzed,and proper suggestions to the adjacent buildings are presented. |
