VISCOELASTIC APPROACH TO MODELING PERFORMANCE OF BURIED PIPES

The development of a viscoelastic solution for the displacements, strains, and streses in pipes from an elastic analytical solution for a soil-pipe interaction problem is described. The solution includes the time dependence of the defelections, stresses, and strains in the soil surrounding the pipe. An example problem is formulated to compare differences in the behavior of a rigid, a thermosetting plastic, and thermoplastic pipe in a typical buried-conduit problem, using the proposed viscoelastic method. This example shows the versatility of this method. It also shows the different behaviors of the different groups of pipes. The results demonstrate that the successful performance of buried pipes depends on working within the limitations of each pipe's material properties. Another use of this solution is illustrated in the use of deflection data measured with time in a laboratory load test to back-calculate the time-dependent properties of the surrounding soil.
