Evaluación y comparación del factor de seguridad contra la licuación para un proyecto de la Isla Mocolí ubicado en el Cantón Samborondón, utilizando metodologías para ensayos de penetración estándar (SPT), ensayo de penetración de cono (CPT) y pruebas geofísicas MAM Y MASW para determinar ondas de corte (Vs).

Abstract

High magnitude earthquakes are frequent in Ecuador’s storyline; therefore, liquefaction is a mayor hazard while analyzing saturated sands. It can cause structural damage to buildings, highways, bridges, etc. if an excepted earthquake hits susceptible sands that were not spotted in time. Nowadays, liquefaction in sandy layers is measured by many processes that are based on the simplified method. (Seed & Idriss, 1971). This work will present the analyses of liquefaction potential for SPT, CPT andVs methods for a project in Mocoli Island, Samborondon. In order to measure the liquefaction susceptibility of a specific layer for SPT and VS tests, (Bray & Sancio, 2006) and (Boulanger & Idriss, 2006) methodologies were applied. On CPT (Boulanger & Idriss, 2014) methodology was used as well, combined with correlations on IC vs FC in order to find the definitive CFCvalue for the site. The methodologies used for liquefaction potential evaluation were: Boulanger & Idriss (2014) for SPT and CPT and Kayen et. al. (2013) for Vs. Afterwards tests were visually compared on a graphic with FS, LPI and vertical settlements all caused by liquefaction.
