摘要
以三泉隧道为研究背景,通过数值模拟和现场试验,探讨了钻爆法施工中喷水软化围岩防止岩爆的效果,结果表明,围岩喷水软化后,降低了围岩的强度和切向应力,释放了围岩的应变能并降低了岩爆发生的等级。
The research background of the paper is the construction of Sanquan tunnel, through the numerical simulation and field test, discussed the effect of preventing rock burst in drilling and blasting construction. The analysis show that weakens the strength of rock and tangential stress, releasing stress-strain and reducing the grade of rock burst after softening.
