The calculation of deformation of pipelines in halo thawing adaptation of the regulatory requirements
The calculation of the strength of the MT in the areas of the halo makes sense for uneven terrain, and rapid assessment of the pipeline deformation possible adaptation of the rules of  to the evaluation of the resource on the beam pipe scheme based on the hypothesis that the deflection largest drawdown. This premise leads to the necessity of solving the inverse problem of structural mechanics – the search distance pipeline deformation (i.e. flight) on the deflection under uncertain boundary conditions. The mathematical models and software algorithms allow operatively to predict the stress-strain state, emergency risks of exploitation and make recommendations, if necessary, adjust constructive solutions of the pipeline network in particular – in geologically complex Siberian route-ray pipeline system "Eastern Siberia – Pacific Ocean "(ESPO-2). Set out the original methods of computer modeling of rainfall and tension of the status of main pipelines in halo thawing in areas of permafrost. The calculations of resource strength of the pipeline on the part of the route of the ESPO-2.
