摘要

锚固浆液的兼容性不理想、类型发展的滞后性成为制约土遗址锚固技术发展的关键问题。为了丰富锚固浆液类型和提高其兼容性，研究以传统材料生石灰为掺料，通过其与质量浓度为1.5%的SH黏结剂、黏土和粉煤灰拌和组成的SH-（CaO+C+F）锚固浆液进行流动性测试以及结石体进行物理、力学特性测试，确定了水灰比为0.5的浆液作为优选浆液。并以该型锚固浆液与2种不同材质的锚杆，在3种长度为变量的条件下组成的6种锚固系统开展原位试验。原位试验以获取6种锚固系统的破坏模式、极限荷载与极限荷载?位移特征以及锚固段应力沿锚固深度分布特征为目的，并对其进行分析与讨论。最后，通过对锚固力学机制的分析，对比并评价了该型锚固浆液的兼容性和锚固性能。该研究结果为土遗址锚固浆液的多样性选择提供了参考。

Abstract

The incompatibility and the lag of type development of anchorage slurry have become the key problems restricting the development of anchorage technology in earthen sites. To improve the compatibility and enrich the types of anchorage slurry

the fluidity of SH-(CaO+C+F) anchorage slurry composed of traditional quicklime

clay and fly ash was tested

so did the physical and mechanical properties of stones. During the tests

the mass concentration of SH binder was 1.5%. Then

the anchorage slurry with water cement ratio of 0.5 was selected as the preferred slurry. Based on this

the in-situ anchorage test was performed in which six different kinds of anchorage systems composed of the selected slurry and two different kinds of anchorage bolts were tested at three variable lengths. The in-situ test aimed to obtain and analyze the failure modes

ultimate load and ultimate load-displacement characteristics and the distribution characteristics of stress along anchorage depth of six kinds of anchorage systems. Finally

compatibility and anchorage performance of this type of anchorage slurry were compared and evaluated through analysis of anchorage mechanics mechanism. The research results provided a reference for the selection of anchorage slurry diversity of earthen sites.
