• The paper describes a procedure for the evaluation of the effect of tensial strength on stability of slopes. The procedure is based on variational approach to limiting equilibrium problems. Based on this approach it was found possible to estimate the depth of tension cracks, and their effect on slope stability in a consistent manner. Formulas and charts which enable the determination of the depth of tension cracks and stability number for every combination of slope angle, mobilized friction, and tensial strength are given.Based on this analysis the following conclusions may be presented : a) The maximum depth of tension cracks is 25% of the slope height, and this value occurs for vertical slopes.b) The increase in stability number (decrease in critical height), which corresponds to a maximum crack is of the order of 20%. This is valid for cracks which are not filled with water.
