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.
