Abstract
A total number of 9 static and 6 cyclic centrifuge tests
on laterally loaded piles in very dense, dry sand was erformed. The prototype dimensions of the piles were 1 meter in diameter and penetration depths varying from 6 to 10 meters. The static tests were used to investigate the initial subgrade reaction modulus and as a reference for cyclic tests. For the cyclic tests the accumulation of deflections and the change in secant stiffness of the soil from repetitive loading were investigated. From all the tests carried out accumulations of deflections were seen. rom the centrifuge tests it was seen that no reduction occurs of the overall bearing capacity and that deflections accumulate due to cyclic loading. This paper presents test results and discusses the effects from load eccentricity and effects from cyclic loading with focus on accumulations of the deflection and the change in secant stiffness.
