Full Scale Loading Tests on Instrumented CFA Piles
Continuous flight auger piles (CFA) procedure allows the rapid installation of piles with diameters usually ranging from 0,4 to 1,0 m and a length up to 30–35 m, free from the vibration and noise of driven piles and substantially reducing the ground loosening of bored piles. CFA are becoming increasingly popular in many countries, and sometimes they are claimed to have the advantages of both driven and bored piles, without the related shortcomings. The behaviour of CFA piles, however, is actually affected by technological factors; among them the capacity of the equipment in terms of thrust and torque and the volume of concrete pumped in during auger retrieval. In the paper the results of three failure loading tests on instrumented CFA piles are presented. The analysis of the observed behaviours confirm that the CFA piles are somewhat intermediate between bored and driven piles.
