6、intended for the conveyance of sewage, industrial waste, storm water, and drainage. The standard practice covers the direct design method, manufacturing specification, and standard installations. It is based on research and testing over the past twenty years to develop a more rational design procedu

The direct design method is an improvement on the indirect design method based on the three-edge bearing test which does not represent the soil pressu
8、re distribution around an installed pipe. The soil pres- sure distribution on a buried pipe depends on soil-pipe inter- action, which in turn depends on the soil material and instal- lation procedure. The direct design method provides the procedure for determining the pressure distribution coeffi- c

The limits state de- sign procedure specified for the design of pipe is consistent with the procedures outlined in Section 17 of the AASH
