Upper limit of Passive Lateral Soil pressure
Upper limit of Passive Lateral Soil pressure
(OP)
Is there an upper limit generally accepted for the amount of passive pressure that can develop, either for resisting movement in a sheet pile wall or resisting movement in a large drilled pier??

One item of note on passive pressure: Watch for strain compatibility. Just because the soil can offer an elevated amount of passive resistance, doesn't mean you want to realize that much movement for the resistance to develop.
Another item of note: DM-7 (I think it's 7.2, but it may be 7.1) has the log-spiral passive pressure charts and these are always much greater than the Rankine Kp value. There are cases where I could use more than 3, either when I'm not worried about strain compatability and I'm dealing with an open-graded aggregate (i.e., with a phi of 40 degrees or so. . .).
