Abstract:A problem of strength of a main pipeline in its zone of rectilinear overground passage through an obstacle is considered in the given case. In the given case. It is not the overground multi-support segment alone that is included in the calculation, the adjacent underground parts which are situated at a certain distance from the ground are also taken into account here. The pipeline is described by a beam model with piece-wise constant rigidity, i. e. each segment of the pipeline i of constant rigidity. This all… Show more
