Thrust Restraint Design Equations And Soil Parameters For Ductile Iron And PVC Pipe

These equations and soil parameters are an effort to provide the piping system designer with conservative techniques and parameters for the design of underground restrained joint piping systems. They utilize recognized design equations and conservative soil parameters. The design equations in this handbook have proven useful in a wide variety of applications since 1982. The soil parameters presented include the results of an extensive study of the actual frictional performance of soils on ductile iron, ductile iron encased with polyethylene, and PVC pipe.
