坑道头部不同加固措施的抗爆性能试验研究

Experimental Study on Anti-detonation Quality of Different Reinforcement Measures at Tunnel Portal

通过大比尺抗爆现场试验,分析研究了坑道头部三种不同加固措施在顶爆条件下的宏观破坏特征,对防护工程头部不同加固措施的抗爆性能进行了比较分析,为坑道头部的安全设计和加固改造提供试验依据。

This thesis studies and analyzes the macroscopic destruction characteristic of the reinforcement measures at the tunnel portal under the dynamic loads,and compares with the anti-detonation quality of the reinforcement measures through large-scale on-the-spot experiments of anti-detonation,which provides the experimental basis for the reinforcement and reconstruction of the tunnel portal.
