## Abstract

The CPT-q_{c} has been used quite successfully to estimate the shaft friction f_{s} along vertically loaded piles. This prompts the question of how to use the q_{c} to estimate the ultimate laterally loaded pile resistance p_{u}, as the correlation between q_{c} and p_{u} is not as strong as that between q_{c} and f_{s}. In this paper, modulus of subgrade reaction k and the p_{u} profile were deduced using closed-form solutions and measured response of eight laterally loaded rigid piles tested in-situ and in 1g model tank, respectively. A good comparison is made for each test using a constant k and linear increasing p_{u}. The deduced values of k and p_{u} are consistent with those gained previously for 57 lateral piles. Particularly, the gradient of p_{u} over q_{c-average} for the short piles is equal to (1.8-8.8)%, which is only a fraction of other suggestions. This difference necessitates further study on the correlation between q_{c} and p_{u}.
