摘要：
Based on the analysis of stress distribution, limit-equilibrium realm and displacements of soft rock tunnel maintained by whole section bolting-grouting reinforcement method, the mechanism of whole section bolting-grouting reinforcement is systematically discussed. The formulae of bolting-grouting parameters are put forward. Through the in-situ tests of traditional bolting and shotcrete method and whole section bolting-grouting reinforcement method, the theoretical and practical values of whole section bolting-grouting reinforcement are verified.
