Análisis de las correlaciones entre propiedades índice y mecánicas con la resistividad eléctrica de suelos granulares en la zona 1 de la ciudad de Ambato

Abstract

The present investigation was made considering ten points of the Huachi Chico Parish of Ambato city, which aims to determine correlations between index and mechanical properties to the electrical resistivity of granular soils among which the moisture content, the granulometry, Atterberg limits, specific gravity, compaction, standard penetration test and CBR; the approach of the hypothesis can be verified by performing the field tests and laboratory. Once the respective tests were made, it was found that the hypothesis is correct and it is possible to establish the correlation between each test performed, then the tabulation, analysis and interpretation of the data was obtained in the field and laboratory work. The values obtained by the tests of resistivity ratios and mechanical properties were analyzed statistically by the least squares method to establish whether there simple correlation or multiple between variables, in some cases not all the points were worked because they generate values waste squares very high relative to the trendline generating a lower correlation. After analyzing the results by the least squares method was established that the determination coefficients vary from 58 percent to 94 percent, indicating that there are good and excellent correlations respectively between the properties. Thus the probability that the index and mechanical properties of soil can be determined by applying the method of electrical resistivity or vice versa occurs.
