爆破工程风险管理和德胜口隧道光面爆破设计研究

爆破工程属高危作业，迫切需要进行风险管理。爆破工程风险管理的主要内容是安全管理、风险预测及对策研究。以京包高速德胜口特长隧道的爆破工程为例，对其光面爆破进行设计研究。结果表明:隧道光面爆破能有效降低爆破作业对围岩的扰动，控制坍塌安全风险并有利于降低隧道施工成本、加快施工进度。

Risk Management Countermeasures for Blasting Works and Design Study on Smooth Blasting of Deshengkou Tunnel

The blasting works are high-risk works which leading to urgent demand for risk management. Carry out design study on smooth blasting of the long Deshengkou Tunnel of Beijing-Baotou Highway. The results show that the smooth blasting could effectively decrease the disturbance of blasting to surrounding rocks, control the collapse risk, reduce the tunnel construction cost and accelerate construction progress.
