GRP and Reactive Clay

GRP and Reactive Clay

GRP and Reactive Clay

(OP)
Hi,


This was previously posted in the Civils/Environment Forum but got no responses.

I am researching the behaviour of GRP pipe buried in a trench in a designed embedment in reactive clays. I am looking for articles or books that cover the analysis of the soil/pipe/embedment structure.
AWWA standards cover the design of GRP in trenches subject to external loading from soil, vehicles, aircraft etc. However reactive clays are going to provide a pressure from below the haunches resisted by the trench and overburden.

What software is used to model such combined soil/embedment /pipe. Does software eexist that allows the individual analysis of the glass reinforcement, roving angle etc of the GRP amd loads from soil and water table?

I am interested in the stress, strain, combined loading, deflection and buckling criteria.

I have found research on PE pipes in such soil but so far none on GRP.

Your experiences in such installations would also be welcomed.
