Análisis espectral de propagación de ondas para análisis de pruebas de integridad de pilotes
##plugins.themes.bootstrap3.article.details##
An analytical solution is obtained for the problem of wave propagation along a concrete pile. The problem consider a longitudinal element with a piece wise varying section, friction forces along the element and a reaction force at the tip, with a transient stress pulse applied at the top. This problem is representative of low strain pile integrity tests. Different alternatives for the solution of the problem were considered, and the spectral analysis method was chosen and implemented using Matlab. The test was modeled for several cases, comparing the results with actual PIT measurements. The parameters for the analytical model were obtained from numerical models of soil-pile interaction.
