Indian geotechnical journalSummary: Direct shear tests on cement mortar samples with symmetrical and asymmetric toothed structural joints were conducted in this study. The main objective is to study the effect of the left undulation angle (i1), the right undulation angle (i2), and the length (l) of the undulation body on the shear properties of artificial jointed rock samples. The test results show that for artificial rock samples with through-symmetrical toothed structural joints (i1 = i2), there is a significant increase in the shear strength and cohesion c of the test specimens when i1 remains constant and l gradually increases. An increase occurs in the shear strength and internal friction angle φ when there is a gradual increase in i1 and l remains constant. For those samples with through-asymmetrical toothed structural joints (i1 ≠ i2), there is a significant increase in the shear strength and cohesion c of the test specimens when i1 remains constant and l gradually increases, and the shear strength of the specimen first increases and then decreases when i1 increases from 15° to 75° and l remains constant.
