Abstract
This paper analyzed the mechanical properties of the interfacial interaction between the brick slag soil and geogrid in the natural state and in the state of considering the infiltration of rainwater or groundwater via the direct shear test and drawing test methods, and compared them with the mechanical properties of unreinforced brick slag soil. The results show that adding geogrids to brick slag soil can improve the strength indicators of brick slag soil (internal friction angle and cohesion), with an increase in the internal friction angle of 2°-3°. Additionally, the effect of reinforcement on the cohesion of brick slag soil is greater than that on the internal friction angle. The cohesion of natural brick slag soil increases by 1.35 times in direct shear tests and 1.32 times in drawing tests compared to unreinforced soil. When the infiltration effect is being considered, the cohesion of reinforced brick slag soil increases by 1.65 times in direct shear tests compared to unreinforced soil, and increases by 1.54 times in drawing tests compared to unreinforced soil. For brick slag soil in the same conditions, the strength indicators of drawing tests should be greater than those of the direct shear tests, with the strength indicators of infiltrated brick slag soil lower than those of natural brick slag soil. By comparing and analyzing the shear stress and deformation relationship curves, it can be concluded that the direct shear test is suitable for situations where the relative displacement between the brick slag soil and the geogrid is small, while the drawing test is suitable for situations where the relative displacement between the brick slag soil and the geogrid is large.
