摘　　要：锚杆是一种常见岩体内部支护形式,容易与普通支护联合,取长补短,发挥各自的优点。因此,出现了许多联合支护形式,锚注支护就是锚喷和注浆联合的一种较好的支护形式。目前,锚注支护已经得到了广泛的应用,特别是在软岩以及其他不稳定岩层中,发挥着不可替代的作用。分析锚注支护的作用机理,可以更好地在实践中运用锚注支护。通过对不稳定岩层巷道的锚注支护的修复案例,更能发现锚注支护的重要作用。Anchor is a common rock mass,internal support form,easy and common support, learn from each other,playing to their respective advantages. Therefore, there are many joint support forms. The bolt grouting support is a good form of anchor injection and grouting joint. At present,the anchor support has been widely used,especially in soft rocks and other unstable rock strata, which plays an irreplaceable role.Through the analysis of the mechanism of the bolt grouting,we can better anchor the bolt in practice. The important role of the bolt grouting support is found by the case of the anchor grouting support in the unstable rock tunnel.
