【摘要】 分析和研究了爆破振动效应主要控制因素和安全判据。介绍了临近重要保护物、特姝地层中的开挖爆破振动效应与安全判据和隧道爆破开挖对土覆建筑物的振动影响及安全控制。现场测定结果与研究表明,不同条件下的开挖爆破引发的地震波衰减规律不同,并根据质点振动速度,提出了重点文物、岩溶隧道和冻土隧道、地铁等环境条件下的爆破振动安全标准。更多还原

【Abstract】 Based on analyzing researching the main control factors and safe criterion on Blasting Digging, the vibration infection and safe criterion of Blasting Digging on adjacent buildings and surrounding rock of special strata and buildings covering digging tunnels can be analyzed. The results of tests and research indicate that the earthquake waves produced by blasting digging in different conditions attenuation rules are different. Based on vibration velocity, blasting vibration safe criterion about important cultural relic and frozen earth tunnel and Karst tunnel and underground were introduced.更多还原
