Análisis comparativo de ensayos PDA realizados en pilotes metálicos.

Abstract

In this study, the analysis of the results obtained with the Pile Driving Analyzer is carried out, after having performed the dynamic load tests with their respective machinery such as impact hammers for the driving or re-driving process. In addition, the differentiation between the sensors used with respect to their location adhered to the metallic pile is proposed. Prior to the mentioned analysis, soil stratification was done according to its geotechnical properties through borings made in the seaport of the city of Guayaquil. Subsequently, the longitudinal profile, in which the borings and the structural elements analyzed with the sensors through PDA tests were found, was modeled. A comparison was made between the driven elements that were used in the Combi Wall system executed in the project in question; either a simple element as the metallic pile can be called, or an element composed of a pile and sheet piles on both sides aligned to the retaining wall. With the data obtained from the driving process of the selected steel piles, a comparison can be made using the PDA-S and CAPWAP programs that provide measurements of deformation, acceleration, stress distribution, among other relevant records for a correct analysis of the performance of the steel element.
