摘　　要：在隧道施工中,岩爆会威胁施工人员的安全,是施工进程中的严重安全隐患。当前,岩爆预防和治理已成为国际性的技术难题,特别是在高强度岩爆频发的区域,其关乎隧道掘进机械(TBM)的安全与连续作业。为有效应对这一挑战,在引汉济渭岭南TBM第二掘进段施工中采用水锤钻机进行超前应力释放试验。通过收集和分析试验数据,初步确定了在何种地质条件下需要实施水锤钻机超前应力释放孔,并制定了相应的施工参数。这些成果将为隧道施工的工程实践提供有力的参考依据,确保工程的安全高效推进。During tunnel construction,rockbursts pose significant safety risks to workers and create severe hazards to construction progress.Currently,the prevention and mitigation of rockbursts have become a global technical challenge,especially in areas prone to frequent and high-intensity rockbursts,which directly impact the safety and continuous operation of tunnel boring machines(TBMs).To address this challenge effectively,a water hammer drill was used for preemptive stress release testing in the construction of the second excavation section of TBM in the south of Qinling Mountains in the Diversion Project of Han River to Wei River.By collecting and analyzing test data,preliminary criteria were established to determine the geological conditions under which preemptive stress release drilling with a water hammer drill is necessary,and corresponding construction parameters were formulated.These findings provide strong practical guidance for tunnel construction,ensuring the safe and efficient advancement of projects.
