GAS PIPELINE DEFORMATION CAUSED BY FROSTY HEAVING OF SOIL
Abstract
The problem of the underground gas pipeline floating up at frozen ground thawing in the sites, where the body weight of the gas pipeline is less than the pushing out force of the aqueous medium surrounding the site is considered. The calculations are made to determine the conditions of the gas pipeline site movement resulted from the water pushing out force and longitudinal compressive stresses for the cases with partial (with preservation of a frozen ground) and complete ground thawing. The conditions at which the deflected mode of the gas pipeline resulted from its floating-up within the thawed ground layer cannot satisfy the requirements established in normative documents are determined.
