Abstract
UDC 539.3 For polyethylene pipes with a hollow (cellular) wall, we have proposed a method for the estimation of the stress-strain state arising under the action of soils. We have considered two modes of the loading of a cellular pipe: with a rigid base and with subsidence into the soil. We have established which of the building standards for pipes with a solid wall should be used in the calculations of pipes with a hollow wall. We have calculated the critical deflections of pipes and determined the criteria that must be used for the assigned geometrical and mechanical parameters of pipes and soils.
