摘要
针对深埋隧洞高地应力岩爆的具体特征,结合现场实践进行试验论证和工艺改进,探讨在TBM法和钻爆法两种开挖方式下岩爆主动防治的方法,总结出了一套适用于高地应力岩爆段的施工应对措施和灾害控制技术,运用实施效果良好,可供类似工程参考。
Considering the features of high stress rock burst in deep-buried tunnel, this paper carries out demonstration testing and process improvement combining with field construction practice, and discusses active control methods for rock burst with two different tunnel excavation methods, namely the TBM method and drilling blast method. Then, a set of construction response measures and disaster control technologies for high stress rock burst tunnel sections are presented, achieving good effects. It can provide references for the similar projects.
