摘　　要：通过对深圳地铁隧道爆破开挖时爆破震动监测数据的分析和研究,总结出爆破震动对地表建筑物产生危害的主要影响因素,并根据现场测定数据,拟合出地震速度、药量大小与爆源距离之间关系式。现场测定结果与研究表明,以爆破振动速度标准作为地面建筑物的安全判据是合理和可行的,并确定了地铁隧道爆破的安全判据,为隧道掘进的振动危害控制提供参考。Through the analysis and study of the blasting seismic data supervised in Shenzhen Metro tunnels blasting excavation, the main harmful factors affecting surface buildings have been generalized and the relation formula concerned with Seismic velocity, dynamite and the distance from blasting point has been obtained. The results of tests and research indicate that taking the seismic velocity as a safe criterion of the building structure in tunnel blasting is rational and effective, and the safe seismic criterion rules can be put forward as a reference on reducing the blasting damage and the vibration effects in Metro tunnel blasting.
