Contribución De Las Frecuencias Características Al Periodo De Vibración Dominante en La Ciudad De Querétaro, México

Abstract: RESUMENEn este trabajo se presenta la metodología desarrollada para evaluar la contribución de la frecuencia característica de cada estrato al período fundamental de vibración a partir de la inversión de las curvas de dispersión aparente obtenidas del levantamiento en campo de ondas superficiales con fuente activa, sin importar la velocidad de cada capa. El cálculo del período fundamental se realizó con el procedimiento simplificado de un medio estratificado lineal desarrollado por Dobry et al. (1976). Como re… Show more

“…The objective of these is to measure the propagation time of seismic waves generated with the help of a hammer or by the detonation of explosives, which propagate vibrations in the ground that are measured by sensors (geophones) placed on a straight line of known distance between point A and point B called refraction line [16]. The importance of performing this test lies in that through a series of calculations and procedures it is possible to know very important parameters such as the speed of wave propagation and the vibration frequency in the sector, the latter with relevant characteristics since when the fundamental period of the site is close to the predominant period of the earthquake, harmonic amplification or resonance develops, resulting in a large horizontal acceleration of the ground surface [17].…”
