In the present paper, two major types of soil weakness are considered: they can occur either due to structural damage in the material or due to interlayer contact. The influence of soil weakness on the results of stability calculations was investigated using a real example - a slope with stability-loss hazard. The strength of particular soil layers was examined by strain-controlled undrained triaxial compression tests with pore pressure measurement, whereas the shear resistance for the brown coal-clay contact was determined in a direct shear apparatus. Numerical analysis of slope stability was performed using the modified Janbu method. It has been found that an adequate assessment of soil-structure disturbance and the knowledge on the shear resistance in the contact zone are of paramount importance to the stability analysis of a slope which consists of hard soil series.
