Abstract: There are different opinions on the influence of tensile strength on the stability of homogeneous slopes, especially for slopes with different inclinations. Based on the composite tension-shear Mohr-Coulomb criterion provided by the finite difference program FLAC3D, a series of numerical calculations were carried out for several typical homogeneous slopes by using the strength reduction method. The influence of soil tensile strength on the stability of slopes with different inclinations was studied. The results show that the steeper the slope is, the greater the influence of soil tensile strength on the safety factor of the slope. The value of soil tensile strength has great influence on the safety factor, deformation, and failure characteristics of vertical slopes. The influence on 45° inclined and gentler slopes is relatively small; while for the steep slope inclined over 60°, the variation range of the slope safety factor caused by different soil tensile strength can reach more than 10%. Therefore, special attention should be paid to the soil tensile strength in the stability analysis of steep slopes, so as to avoid the calculation results being too dangerous or too conservative because the selected value of soil tensile strength is too large or too small.

Key words: slope stability, tension and shear, composite failure criterion, tensile strength, strength reduction method
