EXPERIMENTAL P-Y MODEL FOR SUBMERGED, STIFF CLAY

A testing program was conducted to investigate the effects of scale, including pile diameter and relative pile-soil stiffness, and number of loading cycles on the p-y relationships. The intent of the study is to add to the data base from which p-y criterion is proposed, based on the analysis of these tests. An independent set of full-scale lateral pile load-tests is described that was conducted in submerged, stiff clay. An improved practical p-y criterion for submerged, stiff clay of the type at the test site (overcsonsolidated, saturated and moisture stable clay with closely spaced, discontinuous slickensides) was developed. This criterion indicates slightly less stiff initial behavior but lower post-peak degradation than the "stiff A" criterion for submerged stiff clays and, consequently, predicts considerable different pile-head behavior.
