Box Culvert - Settlement under a Embankment
Box Culvert - Settlement under a Embankment
(OP)
I am looking for some advice/guidance on a Box Culvert design under an Embankment that might have two different soils beaneath, which might cause differential settlement.
Is there maximum differential settlement that a box culvert can tolerate? In terms of structural design, do you guys have any advice on what needs to be done, to design this box culvert for differential settlement?
Thanks

No, there is no specific value limiting the amout of the settlement. The limiting factors will be the amount of distortion the structure could handle without damage or distress.
Typically, in the ares where the differential settlement is expected, the culvert should be divided into section with some kind of flexible joint, allowing for some movement. Other option will be to use prefabricated corrugated metal culverts (pipe or arches), which could handle very large differential settlements.
