锚固和复合锚固类结构抗动静性能研究概述

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。

Overview of research on the dynamic and static performance of anchoring and composite anchoring structures

Anchorage type structure refers to the grouted anchor, anchor cable, soil nails and reinforced soil a class of geotechnical engineering reinforcement support structure. Composite anchorage structure refers to a class of geotechnical engineering reinforcement and support structure in which each single anchorage structure is used in conjunction with each other or with traditional engineering methods and structural measures. It has been proved and confirmed that anchorage and composite anchorage structures have excellent dynamic and static load resistance, and some of them have been successfully applied in a large number of structural types. However, there are more researches and applications on static load resistance of anchored and composite anchored structures and relatively few researches and applications on dynamic load resistance. This situation is similar at home and abroad. Some anchorage and composite anchorage structure types, such as foreign energy-absorbing anchorage and yielding anchorage structure, China''s new composite anchorage structure, have their own characteristics, especially with great potential to resist dynamic loads and cost-effective ratio. Their use for static loads can also be explored. Although the tests on these structures are preliminary, only completed the effect test, have not yet done in-depth mechanistic studies, but the development prospects are promising, worthy of attention, reference and further discussion.
