摘　　要：隧道爆破施工引起的周边围岩的不利振动直接威胁到临近构筑物的稳定及安全,因此控制隧道爆破施工显得格外重要。文中阐述通过设计爆破参数及采取合理的支护措施,有效地降低了施工风险,提高了作业效率,供类似工程借鉴和参考。The adverse vibration of surrounding rock caused by tunnel blasting directly threatens the stability and safety of adjacent structures,so it is very important to control the tunnel blasting construction.Through the design of blasting parameters and the adoption of reasonable support measures,the construction risk is effectively reduced and the operation efficiency is improved,which can be used as reference for similar projects.
