Behavior and Design of Buried Concrete Pipes

This report presents the findings of a year-long research project, where an in-depth review of the available concrete pipe design methods and the Nebraska Department of Roads (NDOR) pipe design policy is conducted. In this chapter, the project’s significance, objectives, and tasks are presented. The findings from this study suggest that the NDOR policies can be updated as follows: The existing fill height tables can be updated (Chapter 3) and then expanded to include more design options for the pipe designer and manufacturer. All proposed changes would be validated through laboratory experiments. The research team also envisions substantial contributions can be made to the current pipe design practice at a more fundamental and nation-wide level. This research could develop a unified, efficient design method that eliminates the confusion and discrepancies between the current design methods. The research team’s review of existing procedures indicates that based on the current standard inventory of concrete pipe available from Industry, the Nebraska Department of Roads (NDOR) is appropriately using the Direct Design to determine fill heights, as shown in Table 2 Fill Height Table Comparison.
