Abstract: The type of anchorage slurry and its compatibility with blot and slurry are the research focus in the field of earthen sites’ anchorage. Glutinous rice soup was used as major cementing material modified by mixing with clay and fly ash. The experimental program examined three anchoring systems, i.e., wood, glass fiber reinforced plastic, and steel rebar, cemented by modified glutinous rice mortar. The test monitored the ultimate load, load-displacement characteristics, stress-strain on the blot-slurry interface, and the response extent of interfacial monitoring point strain on load step. The preliminary analysis of the mechanism of the anchorage concludes that the anchorage performance the system highly depends on the mechanical compatibility of blot-slurry, which is further determined by its force mechanism, deformation and strength characteristics ultimately. The research results provide a basis and reference for the application of modified mortar mainly made of glutinous rice soup in the field of earthen sites’ anchorage.

Key words: modified glutinous rice mortar, earthen sites, anchorage performance, deformation compatibility, mechanical compatibility
