DEVELOPMENTS IN SEWERAGE - 1. CHAPTER 2. STRUCTURAL DESIGN OF PIPELINES

The current procedures by which sewerage pipelines are generally structurally designed are reviewed, both as regards pipes of rigid materials and those of flexible materials, and areas in which developments have taken place are noted. Theoretical formulae are given by which the loads imposed by the backfill under various conditions of installation may be determined and also the loads transmitted to the pipes from surface surcharges. Common methods of bedding the pipes are mentioned, and practical considerations including the effects of variations in workmanship are briefly discussed. (Author/TRRL)
