This book covers the structural analysis and design of buried gravity flow conduits, including traditional pipes, arches, box conduits and buried bridges with spans up to 80 ft (25 m) and greater. The text primarily covers concrete, corrugated metal, and plastic conduits, but is generally applicable to other materials. Applications include culverts, storm drains, sewers, and pedestrian and vehicular crossings. 
The book is intended to introduce the subject to practitioners new to the field as well as provide detailed information for those with prior experience. The opening chapter presents historical background and basic design models to introduce important concepts and then follows with chapters devoted to materials, soils, soil-conduit interaction, and guidance on the use of finite elements for analysis. Then design methods for evaluating soil-conduit systems are presented along with guidance on important considerations during installation. The book concludes with field experiences of when things went wrong and why.
Analysis and Design of Gravity Flow Conduits and Buried Bridges offers a unified and comprehensive guide for practicing engineers working on buried pipe design, private consultants, and product manufacturers, as well as researchers in the area.
