Análisis comparativo entre la humedad gravimétrica y la humedad determinada con sensores electrónicos en suelos granulares del cantón Ambato. Provincia de Tungurahua

Abstract

Through time within the construction of different civil works, water has played a very significative role due to its importance within the branches of Civil Engineering (hydraulic, soil mechanics and structures) based on this, different standards and techniques are established depending on the use or the way in which this very important resource will be used. In the present experimental work, water was analyzed as a component in soil, implementing the alternative model to determine the humidity content of soil granules within the Ambato Canton, by means of applying electronic resistance and capacitive sensors, correlated to the reliable information obtained by means of soil normed tests. (Norms ASSHTO y CFE 10000-73). Once the results raised in the field were tabulated, comparisons were realized with the help of the program Excel, obtaining simple and multiple correlations to estimate coefficients corelated, classifying the qualitive and quantitative tests (from regular to excellent) detailing that the electronic sensors give optimum behavior (above 90 percent), those in the evaluation of the humidity content in the Proctor tests from 15 of the samples taken from the parishes in the Ambato Canton. This analysis permits obtaining the values of the humidity content of the site, limiting the time to obtain the results very similar to the values of the standard tests, its use is recommended to carry out the previous soil sample studies, with a low cost and excellent workability.
