The overburden correction function
The overburden correction function
(OP)
I don't know the overburden correction function and the shear stress correction function which influence the cyclic stress required to tirgger liquefaction.It seems that Kramer's book (Geotechnical Earthquake Engineering)has the answer.But I Can't find that. who can help me?I 'm in hurry.
thanks very much.
thanks very much.





RE: The overburden correction function
Boulanger, RW (2003) "High Overburden Stress Effects in Liquefaction Analyses in the December 2003 ASCE JGGE for K-sigma
Boulanger, RW (2003) "Relating K-alpha to Relative State Parameter Index" in the August 2003 ASCE JGGE for K-alpha.
Be aware that K-alpha is quite dependent on density as well as alpha, and it doesn't always increase with increasing alpha.
Bon chance!
