| Summary: | In the proposed article, the behaviour of a foundation slab resting on the linearly deformable bed and characterized by the modulus of deformation variable in x- and y-axis directions is considered. The modulus of deformation and the load distribution are based on a regular pattern that features the following parameters: modulus of deformation mean =25МРа coefficient of variation =0,2, load distribution mean 0,5 МРа; coefficient of variation =0,1. Correlation coefficients between 1, 2...=0As a result of the research, the authors have identified the empirical deflection to approximate the theoretical load distribution. The research has demonstrated that both deflection and slope values follow a regular load distribution pattern. If the deflection value exceeds 20 cm and the slope value exceeds 5cm, the structure fails. Therefore, the theory of probability may be applied to assess the probability of failure of any structure.
