Abstract

Measured waves in integrity test for foundation piles are influenced by the soil restriction. Therefore, it is important to grasp the influence of the soil restriction in order to interpret the measured signal. In a laboratory, the influence of soil restriction was estimated by analyzing the waves which were measured by integrity test on the model piles set up in a man-made ground. Moreover, the velocities of shear waves, which were evaluated from matching the analytical wave to the measured wave by KWAVE-method, one of the one dimensional stress wave analysis methods, gave good agreement with the velocity of shear wave which had been obtained directly by the soil investigation. It was confirmed that KWAVE-method can be applied for foundation piles and the characteristics of ground can be estimated by calculating from the deformation modulus assumed by the method of signal matching.
