The article proposes to consider the possibility of using pipes from ductile iron with spherical graphite in the construction of oil pipelines to solve the problem of corrosion formation. In addition to corrosion resistance, such pipes also have other positive properties. A comparison is made with steel pipes, and the basic physical and mechanical properties of ductile iron with spherical graphite are also considered.

Within the framework of the kinematic model, calculation formulas are obtained for determining the deformation of a water-saturated base from weak soils, taking into account vertical reinforcement and the bearing capacity of pore water. Theoretically justified the use of vertical reinforcement, aimed at strengthening the bearing capacity of the soil base.
