Consideration is given to the direct and inverse problems for pipeline bending both by gravity and transported fluid. The effect of internal pressure drop and the velocity of a fluid are taken into account. The influence of point fixing of “pipeline-capacity” constructions for the deflection is also taken into account. The inverse problem is to determine the relative stiffness of distributed support under the instrument determining pipeline deflection or deformation of its outer fibers. The method of loading pipeline by the concentrated power and determination of appropriate instrument deflection or deformation is applied. In particular, loading and corresponding measurements are carried out at the midpoint of the pipeline span.
