Abstract:
Field investigations concerning screw piles and columns have been carried out for the “Bearing
capacity and work in the soil of screw piles” research project, financed by the Polish Ministry of
Science and Higher Education – project No N N506 369234. The tests of three instrumented screw
piles were conducted together with CPTU tests and measurements of pile installation parameters
(especially torque). The objectives of field investigations and the entire research project include
discovering how screw piles work in the soil, locating and describing the correlations between
CPTU results and rotation resistance during pile auger installation and next establishing correlations
between CPTU results, rotation resistance and the bearing capacity of this kind of piles. The paper
describes the investigation procedure and the basic results of tests carried out in the first of a series
of sites.
