Comparación de estimaciones de asentamientos de un terraplén en el cantón Durán por diferentes métodos.

Abstract

In this titling work, a comparison of settlement estimations of an embankment in the canton of Durán by different methods is carried out. The project starts by performing two tests, CPTu and Spt, using Shelby tubes for sample extraction. Once the tests have been carried out, the samples obtained are taken to the laboratory for analysis. The following tests are performed on these samples: Onedimensional compression, Atterberg Limits and Moisture Content. Once the results of these tests are obtained, they are interpreted, and the necessary parameters are obtained to make the settlement estimation. From the results of the one-dimensional compression test, Casagrande's graphicmethod is used to obtain the preconsolidation stress and the compression and recompression indices, the Schmertman correction is also used for normally consolidated clays and the Terzaghi and Peck correction for overconsolidated clays toobtain a new compression index, empirical correlations are also used to obtain other values of compression and recompression indices and to find the one that best suits thereality of our soil. From the data obtained from the CPTu, the restricted modulus will be used as an essential parameter for the estimation of settlements by this method. Additionally, the consolidation coefficient was calculated and from this, the time in which 90% and 50% of soil consolidation will be reached.
