Study of surface movement of a shallow-multilayered soil under Pwaves

In this work it was designed and implemented an experimental setup to study the surface acceleration of a multilayered soil and the experimental measurements were contrasted with a one-dimensional theoretical model based on ray tracing. For this purpose, a soil was suited, where tiles and expanded p...

Description
Summary:In this work it was designed and implemented an experimental setup to study the surface acceleration of a multilayered soil and the experimental measurements were contrasted with a one-dimensional theoretical model based on ray tracing. For this purpose, a soil was suited, where tiles and expanded polystyrene (EPS) slabs were buried. This soil was disturbed by a sound wave at normal incidence from a subwoofer. In experiment were obtained resonance frequencies which are according to the studied theoretical model. En este trabajo se diseñó e implementó un montaje experimental para estudiar la aceleración superficial de un suelo formado por capas y se contrastaron las mediciones xperimentales con un modelo teórico unidimensional de trazado de rayos. Para tal fin se preparó un suelo donde fueron enterradas placas de poliestireno expandido (EPS: Expanded PolyStyrene) y baldosas. Dicho suelo fue perturbado por una onda acústica bajo incidencia normal proveniente de un parlante. En el experimento se obtuvieron frecuencias de resonancia que están de acuerdo con el modelo teórico estudiado.
