El uso de pruebas geofísicas de velocidades de onda (Vs) como complemento a las herramientas geotécnicas para determinar la punta de cimentación en pilotes diseñados a rechazo hasta profundidades de 30 metros.

Abstract

Applied geophysics has taken a breakthrough for engineering purposes where this knowledge can be used for different purposes, there are non-destructive geophysical methods that allow to deduce the dynamic characteristics of a site. The main objective of this research is to study the application of multi-channel analysis of surface waves in their active and passive variants, to obtain the profile of shear wave velocities. This research will focus on the determination of the resistant layer for the tip of the piles of the structure for access to the new port of Manta, by using different sources in active trials, studying the geometric properties of the arrangements of geophones in passive measurements , and the combination of the results obtained with both techniques. These tests will be used as a complement to other geotechnical tools. The results of these tests will be compared with the peak of the piles driven into the project, and it is proposed to analyze the use of these tests to determine efficiently together with the traditional method of drilling.
