Stress state of a soil array at break o the pipeline

Vladimir Andreev and Anatoliy

Abstract

The rupture of water and sewer pipes leads to numerous accidents (subsidence, swelling, etc.). This is especially characteristic for clay, loess, peat and other soils. We considered the stress state of clay array at different models on fluid propagation from a fracture site. Accordingly, the problems are solved in cylindrical and spherical coordinates. The problem is solved by the methods ofstationary andnon-stationary moisture elasticity. The feature of the calculation is the accounting of the inhomogeneity of the clay during moistening.
