in a buried pipe, the stresses and displacements produced during placement and compaction of the backfill are difficult to predict theoretically because their values are strongly influenced by the construction procedures employed on site. however, the displacements and stresses produced by the weight of the materials and loads applied to the completed structure are amenable to direct theoretical analysis. in the past, fairly simplified theoretical models of the pipe-soil system have been employed by design engineers for predicting the stresses and displacements. however, with the advent of the finite element technique, more realistic theoretical models can be employed. this report compares the finite element analysis of the structural performance of a 1.83 m internal diameter steel pipe with experimental field measurements carried out on such a pipe. the calculated results are in good agreement with the experimental values. this suggests that the finite element method could be useful for the structural design of large-diameter buried pipelines. one of the advantages of using this method is that no prior assumption concerning the soil-pressure distribution around the pipe is required.(a)
