| 摘 要： | 锚注支护是将锚喷支护与注浆加固有机结合的一种主动支护方法。根据其机理，将注浆锚杆简化为作用于围岩的一种体积力，并将注浆作用看作对围岩力学性能的改变，以此建立了锚注支护的力学模型。依据围岩流变特性的试验结果，选择了一个适合的流变模型。最后应用粘弹性理论，分析了锚注支护对具有流变特性围岩在维护其稳定性方面的作用，计算结果表明，锚注支护对维护破碎围岩的稳定具有显著效果。

| Abstract: | Bolt-grouting support is active method to combine bolt-spouting and grouting. In light of its support mechanism,a calculating model about its deformation is derived by means of action of bolt represented by volume-force and action of grouting regarded as improvement of properties of rock masses. The action of the support in preserving stability of surrounding rock masses is analyzed and its effect is proved being remarkable with using Kelvin-Voigt model and visco-elastic theory. |
