Trenching for pipelines
Trenching for pipelines
(OP)
Pipelines are going to be placed in a trench of 4 m wide. The invert of pipes would be 5 m below the surface ground elevation. Ground is sandy silt (SPT=11), clayey silt (SPT=17), clayey sand (SPT=4) and below 7 m depth silty sand (SPT=15). Groundwater table is high.
We are using pre-fab cage with steel plates.
Could someone please advise 1-2 references/design manual to design the above trench - including heave, embedment length. Thank you very much.

Potential quick conditions from groundwater. Be careful of sand layer at bottom. Assume you will dewater well below this level.

Wonder if there is a more recent reference which may take all the above into account. Thank you.
