摘　　要：在采石场爆破规模和药量控制范围确定条件下,通过对隧道监测到的测点振速和爆源距,分析了爆破振动对隧道的影响,并给出了爆破振动速度衰减公式。分析了爆破振动速度对新建隧道已建成部分、处于破碎带区域隧道及隧道建设过程中新浇筑混凝土的影响。分析结果表明,采石场爆破振动对隧道建设没有破坏性影响,分析结果为该隧道建设和安全评定提供了科学依据。Under the situation quarry, the influence of blasting of only knowing the scale and scope of blasting explosive used by the vibration on the tunnel was analyzed by the vibration velocity of measure points monitored and distance between blasting center and measure points. The attenuation equation of the vibration velocity was given. The influences of blasting vibration on the completed part of new tunnel, the tunnel which locates in fracture zone, and new pouring concrete in the process of building tunnel were analyzed. The result shows that tile influence of blasting vibration from the quarry on the construction of the tunnel is not destructive, which provides the scientific basis for construction and safe assessment of the tunnel.
