LOAD TESTS AND LOAD TRANSFER ON SHORT BORED PILES. PROCEEDINGS OF THE ELEVENTH INTERNATIONAL CONFERENCE ON SOIL MECHANICS AND FOUNDATION ENGINEERING, SAN FRANCISCO, 12-16 AUGUST 1985

This paper deals with the behaviour of short reinforced concrete bored piles, in holes drilled with bentonite slurry, through the interbedded shales and limestones corresponding to the Taquari member of the Riachuelo formation, a Cretaceous shallow-marine deposit, which makes up the sub-surface material at the Potassio Sergipe Project of Petrobras Minercao Sa-Petromisa. To obtain the actual load transfer profile from piles inserted in the aforementioned ground, two vertical compression tests on piles instrumented with strain-gages and tell-tales were performed. The measured friction and point resistances are presented and correlated, at each test pile, to the sub-surface geological column as indicated by two previous percussion and rotary borings, performed at the same locations. The test results showed the prevalence of the friction (f) over the point (p) resistance even for short piles, although the f/p ratio increased significantly with pile length.
