THE BEARING CAPACITY OF A PILE

PORTANCE D'UN PIEU

The article gives the results of a static loading test carried out on a pile cast-in-situ in Saint-Ouen limestone which is found extensively in the Paris region. The major interest of this test was that it was conducted in a formation, the geotechnical characteristics of which can only be evaluated by pressiometer tests because of its alternative hard and soft layers. Because of the possibility of testing a pile fitted with detachable strain gauge, it was possible to measure the real values of end stresses and lateral friction. The characteristic real loads (qn, qf and ql) were compared to the corresponding predicted loads deduced from pressiometric rules. Furthermore the test showed that the real and the calculated nominal bearing capacity agree within 10%. Attention is drawn to the fact that real distribution of stresses along the shaft markedly differs from that proposed by the pressiometer method, leading in this case to an over estimation of end stresses.
