In the process of blasting excavation of rear tunnel with mall clear distance and large section, it is very important to ensure the safety of front tunnel exposed to blasting vibrations. Based on the six-lane Xiaoyu Tunnel of Beijing-Qinhuangdao Expressway, a blasting vibration velocity distribution law of the longitudinal and transverse sections of the front tunnel was monitored and analyzed during the excavation of the rear tunnel. The blasting parameters of the rear tunnel were dynamically adjusted and optimized, and the safety control measures of blasting vibration were put forward according the monitoring results. The results showed that the vibration velocity on the radial direction of the side wall of the front tunnel was the largest when the rear tunnel was excavated, and it is mainly caused by cut hole blasting. The vertical vibration velocity is slightly lower than the transverse vibration velocity. However, there is little difference between them, and the blasting vibration energy is mainly concentrated in the frequency band of 30~100 Hz. For the vibration distribution on the longitudinal section of the front tunnel, the peak vibration velocity decays with distance, but the vibration velocity on the unexcavated direction is relatively higher, which is 1.2~1.6 times of the vibration velocity on the same excavated distance. For the vibration velocity distribution on the cross-section of the front tunnel, the vibration velocity on the front side is 5~10 times higher than that on the back side. Multi-stage cutting was adopted to optimize the distribution of the holes.12 different delays were adopted to reduce the charge per delay, and the delay interval was increased to 60 ms to control the blasting vibration. The field practice shows that the optimized blasting design can reduce the vibration velocity of the side wall of the front tunnel by about 50%.

在小净距大断面隧道后行洞爆破开挖过程中,如何保证先行洞的爆破振动安全极为关键。以京秦高速双向六车道小峪隧道为工程依托,监测分析了后行洞开挖过程中先行洞纵、横断面的爆破振动速度分布规律;依据爆破振动跟踪监测结果,动态调整优化后行洞的爆破设计参数,并提出了相应的爆破振动安全控制措施。结果表明:小净距隧道后行洞开挖时,先行洞边墙径向振动的速度最大,且主要由掏槽孔爆破引起,垂直向振速略低于切向振速,但二者差别不大,爆破振动能量主要集中在30~100 Hz频段;对于先行洞纵断面上的振动分布,峰值振速总体随爆心距衰减,衰减速率也随之降低;未开挖方向的振速相对较高,约为同等距离已开挖向振速的1.2~1.6倍;对于先行洞横断面上的振速分布,迎爆侧的振速明显高于背爆侧,其中边墙部位迎爆侧振速可达背爆侧的5~10倍;现场针对爆源采用多级复式掏槽,优化炮孔分布,雷管段别增加至12段来减少相应的单段药量,以及增大起爆间隔至60 ms来等措施控制爆破振动,现场实践表明,优化后的爆破设计可使先行洞边墙振速降低约50%。
