Correlaciones múltiples entre propiedades geomecánicas, velocidades de onda de compresión (VP), corte (VS) y datos de clasificación SUCS en el suelo de cimentación del bloque G de la Universidad Politécnica Salesiana Sede Quito - Campus Sur

Abstract

The current research is developed using multiples correlations between geomechanical properties (Cohesion c, Friction angle φ, Elastic Modulus) and number of blows 𝑁𝑆𝑃𝑇 according to the SUCS Classification and data obtained in Geophysical tests; which will help to reduce the number of tests to be performed, resulting in costs and execution times of geotechnical studies in large study areas. Once the study area was defined field tests were done such as, Seismic Refraction, MASW & MAM, to get the compression and shear wave velocities, next a drilling was made using the SPT test where the number of blows was measured, altered and unaltered samples were obtained, for the development of laboratory tests (SUCS Classification and Direct Shear) to obtain the geomechanical properties mentioned before. For the analysis of variances (ANOVA), the database was added to the results obtained from the soil study at Block G and the nearby stations of the Metropolitan Public Company Metro de Quito, to determine the statistically representative variables which are involved in the multiple linear regression, which were then subjected to an analysis of residual assumptions and confidence levels to obtain the equations with an adequate correlation coefficient.
