Lateral Earth Pressure Coefficient in Rock

Lateral Earth Pressure Coefficient in Rock

Lateral Earth Pressure Coefficient in Rock

(OP)
Hello Geotechs,

Can we use Jacky's and Rankine formula to calculate the at-rest and passive earth pressure coefficients in rock. If not which approach will be suitable to determine the later earth coefficients in rock.

RE: Lateral Earth Pressure Coefficient in Rock

What kind of "rock" and how uniform and "crack-free" (how flaw-free is the whole and the specifics between every crystal) is the "rock" in question?

RE: Lateral Earth Pressure Coefficient in Rock

That would pretty much be pointless.
Or do you mean the at coefficients of soil against the rock.
For all relative and practical purposes (solid) rock has no lateral coefficients.

Probably something like modulus of elasticity would be a better coefficient.

RE: Lateral Earth Pressure Coefficient in Rock

no you cant its pretty obvious , but i don't know how they do it . I presume you got a slope with apparent discontinuities that threatens its stability . Why not weigh the different blocks
