PEinc, thanks again for your contribution.
And yes, the aashto fig 3.11.5.4-2 was a bit confusing.
you said "PADOT requires use of Rankine earth pressure coefficients". Is this in DM4 or in specification? Or is it just your experience dealing with their design review unit?
Thanks
PEinc thanks for your response.
Have you ever use the AASHTO fig 3.11.5.4-2.
For the special case of vertical wall with sloping backfill, what value of beta should one use.
For example:
phi=34, beta=+32, horizontal bottom of excavation,
I am under the impression that even with a sloping...
In using Caquot and Kerisel method to estimate passive earth pressure coefficient Kp (AASHTO Fig 3.11.5.4-2), for the special case of soldier pile and lagging wall (drilled shaft / H-pile), is it more prudent to ignore wall friction?
I would like the opinions of the more experience engineers...
