Uso de pruebas geofísicas de velocidades de onda (Vs) para comparar las diferencias entre suelo virgen, suelo con relleno compactado y relleno compactado con pilotes hincados en la estación 5 de la Aerovía.

Abstract

The evaluation of the soil is of great concern when starting an engineering project, which is why there is so many research and new methods are found so that they simplify and expedite the work of civil engineers. Hence the study of surface waves and their application in geotechnics as a method that does not alter the terrain and provides necessary data at the beginning of a construction project. The main objective in this research is to use the Multichannel Analysis Surface Wave method to determine if the soil actually changes under different types of foundations and how it affects the mechanical properties. This is, if the soil becomes more resistant due to weight and subsequent consolidation or remains in the same state. These results were achieved through field trials, office processing and the use of computer programs that allowed the data acquired in the field to be processed. Once the graphs of the Wave Velocity of each terrain were obtained, we proceeded to analyze and see that the shallow foundations do not alter the ground below. In the case of the terrain with piles (Deep foundation), quite promising wave speeds were obtained by comparing them with the other terrain analyzed. In some pile tests, the speed of the natural terrain was almost doubled.
