Horizontal Subgrade Modulus

Horizontal Subgrade Modulus

Horizontal Subgrade Modulus

(OP)
Is there a table or a standard empirical chart that has information of horizontal modulus Es for different soils? I do understand that Es is based on p and y, but is there a table that simplifies this issue if load values are not known?

Any help is appreciated.  

RE: Horizontal Subgrade Modulus

For what reason do you need this?  For pavement or mat?  They are treated differently.

RE: Horizontal Subgrade Modulus

For drilled shaft or embedded pole the horizontal sub-grade modulus is usually a function of depth and soil type with units of force per volume, (which is a plate reacting some distance into soil due to a force).

RE: Horizontal Subgrade Modulus

I'd like to know the end game.  How will you use the data?

RE: Horizontal Subgrade Modulus

since you are talking about p and y, perhaps you are designing a laterally loaded pile.  com624 software (aka lpile) recommends some horizontal sub-grade modulus values based on terzaghi's work (which he was reportedly never happy with).  personally, i like vesic's equation because it is a function of the elastic modulus and the poissons ratio of the soil.
