摘　　要：为探讨复杂断面施工条件下采用钻爆法时产生的爆破振动对城市环境的影响,遵循城市地铁施工对地表和建筑物的影响必须满足振动、变形和应力控制标准的原则,以某工程为例,用FLAC3D对不同开挖方法的爆破振动效应进行了数值分析,并与现场实测振动速度进行了比较.结果表明,在该工程的特定条件下,机械和钻爆相结合的开挖方法对环境的影响较小.In order to probe into the effects of the drilling-blasting method for metro tunnel with complicated sections on city environment,based on the principles that the influences of city metro tunnel construction on surface ground and buildings must satisfy the vibration,deformation and stress control standards,software FLAC3D was used to the numerical simulation of an practical project,as an example,and the blasting effects of different excavation methods were investigated.And a comparison between a numerical simulation result and field measured vibration velocity was made.The research result shows that the combination of the mechanical and drilling-blasting excavation methods is a satisfying selection to the practical project.
