Soil Pressure on Buried Pipes 1

[geomane]

Could someone refer me to some references for calculating the pressure imposed on buried pipes by the overlying soil including dead loads and live loads? I also need it to include load factors for bedding class.

This is primarily for the PE Exam. I've searched the internet; however, I can't seem to pinpoint a reliable reference.

Thanks in advance for any help you can offer.

Most any geotechnical reference will get you there. Some of the concrete pipe organizations give some reasonably good procedures as well.

Years back an engineer in Iowa (Spangler) did a lot of work with buried pipes, specifically dealing with loads and pipe stress. He developed formulas, wrote papers, etc.

Just for the heck of it look up his "Imperfect ditch"

I did a search on Google for: Spangler pipe loads

and a number of references came up.

One other reference name Marston

I think he was before Spangler and maybe they worked together also.

I did some deflection analysis for pipes some time ago. I used the attached. It has information about the Iowa method developed by Spangler which OG is referring to. Good luck with the exam !!

try the corrugated metal pipe association handbook, or alternatively the ACPA handbook, both have detailed sections on calculating the loading for flexible and rigid pipes. also, perhaps ACPA Design Data 40

Via Amazon used books I recently purchased the old Armco book "Handbook of Drainage and Construction Products".. Years back I made the mistake of giving my copy away. The used books now sell for under a dollar to a few bucks each, depending on condition. Contains a world of info on loadings. Most is fully suitable today.

Another source is the Ductile Iron Pipe Research Association (DIPRA). See "Design of Ductile Iron Pipe" and "Truck Loads on Pipe Buried at Shallow Depths", at this link:

The main source document used for steel pipeline design under roads etc is API RP 1102, latest version is the 7th edition,

also American lifelines Alliance has some good guidelines which should be able to be used as a reference -

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Thank you all for your responses and your time. These resources will help me both in the exam and in practice.

Google Iowa SUDAS design manual. A lot of good info on their site, including an Excel spreadsheet for pipe design.
