EXPERIMENTAL STUDY OF BURIED FIBER-REINFORCED PLASTIC PIPE

An experimental study of interaction between soil and fiberglass-reinforced plastic pipes was performed in a large laboratory soil box. Seven pipe specimens of different diameters and stiffnesses were tested at various loads and under various laying conditions. Sand and clay were the soil backfill. Five different and independent sets of measurements were taken in each test; vertical and horizontal pressures in the backfill soil, normal and tangential stresses at the pipe-soil interface, radii of curvature of the pipe, vertical and horizontal pipe deflections, and hoop strains at the internal and external perimeters of the pipes. Measurements were taken during backfilling and when superimposed pressures were applied. Short-term effects of load, soil type and density, split backfill, and installation quality on pipe performance were considered. The main findings of the study are analyzed and discussed in qualitative terms.
