Abstract: Fissures in loess belong to the structural planes and has an important influence on the stability and safety of practical projects. The Lintong Q2 loess is taken as research objects in this paper and uniaxial compression tests are conducted to investigate the relationship between the fractured loess compressive strength and the fracture angles. The results indicate that the failure modes of the fractured loess mainly includes fracturing failure, compressive-shear failure and slip-compression-shear failure, and the formation of fracture surfaces of the fractured loess is controlled by the fracture angles. Change in the fracture angles has a significant effect on the stress-strain curve for the fractured loess. When the fracture angles of fractured loess are changed between 0° and 30°, the stress-strain curve of the fractured loess are divided into the compressive densification stage, the linear elastic stage, the plastic yield stage and the residual stage, so are the fracture angles of 90°. There are not four stages as the fracture angles change between 40° and 70°, and the failures of the fractured loess are sudden. With the increasing fracture angles, the uniaxial compressive strength of the fractured loess firstly decreases and then increases with the V shape, which significantly shows the effect of fracture angles on the uniaxial compressive strength of the fractured loess. Meanwhile, the fracture angles have a remarkable control effect on the shear strength of the fractured loess.
