Keyword: geotechnical masonry; single-stage shear test; residual strength; Mohr-Coulomb strength theory;
Abstract: The research is based on grid geotechnical masonry laboratory single-stage shear test, obtained shear stress-shear displacement relationship curve and intensity variation curve under different dry density situation,Mohr-Coulomb strength theory has been used to fit the peak strength and residual strength index. The results showed that: the peak strength and residual strength of grid geotechnical masonry increased following the dry density and normal stress level increases; residual strength is in the range of 80% to 90% of the peak strength; Mohr-Coulomb strength theory can be used for well explaining action mechanism of peak strength and residual strength.
