Stresses on Buried Pipe

Stresses on Buried Pipe

Stresses on Buried Pipe

(OP)
I don't know if this is the appropriate forum to ask this question, but I will give it a try.

Can anyone point me to references that would help me evaluate the strength of a pvc pipe to be installed under a large coal pile?

Thanks, DMcGrath!

My mistake, they want to use HDPE. Is the design procedure the same?

RE: Stresses on Buried Pipe

I suggest you download Australian Standard As 2566.1 & .2. This gives a very comprehensive design guide and installation procedure for buried flexible pipelines.

If it PE you may well direction drill the pipeline.

RE: Stresses on Buried Pipe

The methodology is the same, you need to find the appropriate material qualities for the pipe type you are using.  The Plastic Pipe Institute (plasticpipe.org) USED to have their engineering manual on-line, now it looks as if it will cost you $35.

RE: Stresses on Buried Pipe


A coal pile usually has a large caterpillar tractor on top pushing the material around. The expected loading from the tractor will be much different than what you would expect from just a material pile.

RE: Stresses on Buried Pipe

I'm assuming that the coal pile is more than just a few feet high.  unless your pipe is relatively close to the surface of the coal, the live load from the dozer will probably not affect your pipe.  it will probably be designed for dead load
