通过对目前锚杆荷载传递机理、不同地质模型锚固效果、支护机理、锚杆耐久性及商品化问题进行归纳总结,分析表明:在裂隙发育中硬岩和硬岩中,主要是抑制与裂隙面平行或者直角方向相对位移;在软岩和土砂围岩中,主要是控制隧道壁面径向位移和围岩内部相对位移。支护机理至今仍然不能进行定量解释和正确评价,如何提高锚杆加固的效果等方面需加强研究。这些成果将为我国今后隧道锚杆设计和施工提供理论依据。
Based on the current load transfer mechanism of anchor, anchoring effect of different geological models, supporting mechanism, durability and commercialization of anchor, the analysis shows that: in the development of fractures, the hard rock and hard rock are mainly restrained and fractured Surface parallel or perpendicular to the direction of relative displacement; in soft rock and earth sand rock, the main control of the tunnel wall radial displacement and the relative displacement of the internal rock. Support mechanism still can not quantitatively explain and correct evaluation, how to enhance the effect of reinforcement and other aspects of the need to strengthen research. These achievements will provide theoretical basis for the future design and construction of tunnel anchor in our country.
