摘要

摘要: 针对端锚式锚杆-围岩结构体在长时条件下支护作用的演化机制,建立了端锚式锚杆-隧洞围岩耦合作用的结构模型。进行了结构模型的基本假设：①圆形隧洞；②深埋；③各向等压原岩应力；④均质且各向同性黏弹性围岩模型；⑤一维黏弹性锚杆模型；⑥锚杆对围岩作用力整体为面力。基于基本假设建立了端锚式锚杆-围岩耦合流变理论模型。假设围岩和锚杆均为Maxwell模型时,求解了圆形隧洞围岩应力和位移的径向分布随时间变化的解析解,获得了锚杆轴力随时间演变的理论公式。基于锚杆（索）流变模型,进行了FLAC^3D数值模拟软件的二次开发；并通过数值模拟与理论计算的对比分析验证了理论模型的合理性,分析了端锚式锚杆-围岩耦合流变规律及其影响因素。该模型对于研究地下隧洞的流变力学行为,分析锚固支护结构的长期稳定性,指导工程支护设计具有重要的基础理论价值。
