A Relationship Between Deformation Modulus and SPT N for Gravels
The results of over 200 horizontal plate load tests performed in situ in large diameter boreholes on gravels at various relative densities are used to develop a relationship between deformation...

In Situ Tests for Foundation Vibrations
There are several well established methods of determining shear modulus in situ and these are summarized in this paper. New techniques are being developed for in situ determination of...

Harmonic Vertical Pile Response in Non-Homogeneous Medium
This paper describes the application of the boundary element method to determine the steady state response of vertically loaded floating piles in a non-homogeneous medium in which the...
