The probabilistic model of the impedance matrix of the foundation of a gas tank constructed on piles and resting on a layered soil is constructed. The mean impedance matrix is obtained by a mixed FE-BE method, and the probabilistic model of the impedance is compared with the random impedance obtained with more classical probabilistic methods.
