Passive pressure coefficient
Passive pressure coefficient
(OP)
Hey all. I am designing a concrete deadman to support an incorrectly built frost wall. The soil it will be built in is a medium stiff clay, but I have no soils report on the project. Is there a way to determine the passive pressure coefficient of the soil, i.e. assumed cohesion or something, that will give me an allowable value of Kp. If so, what code would it be found in. Thanks much!

If without success, I will assume sandy/gravel fill to come up a low passive coefficient for trail estimate use. If it works, great. Otherwise, you will need to order a soil testing to get the actual parameters.

Thank you for the good explanation and information. Also, could you explain a little more about the Cp factor?

Brinch-Hanson has published on this value (1966)
Limiting Kp (refer to BigH's post) is a good thing, especially if there is concern on strain compatability.

I guess I just thought this was standard stuff covered in most graduate programs in geotechnical engineering. . .
