Abstract

The mixed boundary value problem for a pipe embedded in soil is solved with two-dimensional modeling. In this type of problem the external stress vector is specified on a part of the surface and the displacement on the other part that constitutes the pipe-soil interface. The materials are assumed to be elastic. It is also assumed that the problem domain is multiply connected. Numerical results are presented for typical examples. Introduction Underground pipelines should support the soil loading and the loads applied on the ground surface. The intensity of surface loads decreases with increasing depth. So the effect of traffic or other surface loads on buried pipelines is relatively minor if pipelines are buried deeply. But these loads have significant effects on shallow
