摘　　要：金鸡山隧洞工程因周边环境极其复杂而存在着突出的爆破振动安全问题。在依据科学的爆破振动安全控制标准,并进行爆破振动跟踪监测及反馈的基础上,应用调整隧洞设计循环进尺、断面分区逐步开挖及微差起爆网路来控制最大单响药量等控制振动的有效钻爆技术,较好地实现了隧洞弱振动爆破的安全控制目标。并通过爆破振动监测成果的分析,取得了此特定工程和周边环境条件下的爆破振动分布特性和响应规律。Jinji Mountain Tunnel Project is in an extremeiy complicated environment with blasting vibration safety problems. Accord- ing to the scientific blasting safety controlling standards, and the implementation of blasting vibration tracing and monitoring feed- back, effective drilling and blasting technology are proposed to control vibration, which contains the control of design cycle drilling length, the sectional stepwise excavation section and detonating networks to control maximum explosive charge. Through these measures the control goal of weak vibration blasting can be realized and blasting vibration distribution characteristics and dynamic response rules in this project and surrounding environment can be achieved through an analysis of monitoring results of blasting vibration.
