简介:锚固类结构是指注浆锚杆、锚索、土钉及加筋土-类岩土工程加固支护结构。复合锚固类结构是指各单一锚固类结构彼此或与传统工法及构造措施等联合使用的-类岩土工程加固支护结构。业已证明和证实,锚同与复合锚同类结构具有优异的抗动静载性能,其中有的结构型式已有大量成功应用。但是,锚固和复合锚同类结构抗静载问题研究与应用较多,对抗动载问题研究与应用相对较少。这一状况国内外大体相近。有些锚固和复合锚同结构型式,如国外的吸能锚固和屈服锚固结构,我国的新型复合锚固结构,均有各自特色,特别是都具有极大的抗动载潜能和效费比。将其用于抗静载也是可探讨的。尽管对这些结构所做试验是初步的,都只完成了效应试验,尚未做深入机理研究,但发展前景看好,值得人们关注、借鉴并进一步探讨。
