NUMERICAL ANALYSIS OF THE STRAINED STATE OF CELLULAR PIPES IN INHOMOGENEOUS SOIL

摘要

With the help of Fourier series, we propose a method for the evaluation of the strained state of cellular underground pipes with regard for the variations of the reaction coefficient of the surrounding soil. As a result, we write, in recurrent form, the coefficients of Fourier series for the averaged components of the vector of displacements of a cellular structure. On this basis, we find the radial displacements of a polymeric pipe along its contour.
