The imperfect trench installation method has been used to reduce earth pressure on deeply buried conduits. Few quantitative refinements to the imperfect trench installation method, however, have been added since the fundamental mechanics of the reverse arching action was proposed by Marston and Spangler. It was found during the course of this study that significant frictional forces develop along the sidewalls of buried conduits and adjacent sidefills in imperfect trench installations. Current American Association of State Highway and Transportation Officials provisions do not consider these frictional forces, but they cannot be neglected in imperfect trench installations as their effect is dominant. The objectives of this study were to study the soil-structure interaction for deeply buried roadway conduits (concrete pipes, corrugated polyvinyl chloride (PVC) pipes, corrugated steel pipes, and box culverts) and the efficiency of the imperfect trench method for their installations. This research identifies variables that significantly affect earth loads, as well as the effects of bedding and sidefill treatments.
