| metadata.dc.description.abstractenglish: | Consolidation settlements are a worldwide problem in different soil types, in which infrastructure works are built to develop a city or community. In the Ecuadorian coastal region, soft clay soils predominate, which generate excessive differential settlements, causing human losses and economic damage. This research aims to evaluate the consolidation of soft clays in Duran-Ecuador by applying preloading with wick drains and comparing it with geophysical tests (pre- and post-application) to analyse the consolidation rate efficiency. The methodology consisted of the following phases: (i) review of reference studies; (ii) analysis and interpretation of existing geotechnical data; (iii) technical evaluation of soil improvement with preloading and wick drains; and (iv) pre- and post-construction geophysical surveys (project serviceability). Soil consolidation analysis with no improvement was expected to require 81 months. At the same time, preloading and wick drains were achieved in 6 months, reducing the consolidation time by 90%. Moreover, settlements between 70-90 cm were excessively high according to the Ecuadorian Construction Standard, whereas settlements between 9- 10 cm were expected by applying the improvement. Using geophysical tests, the improvement in the bearing capacity of the soil was determined through empirical correlations between the variation in electrical resistivity and soil void ratio. The combination of both methodologies (preloading and wick drains) in soft clay soils is an optimal solution for the reduction of consolidation time in the construction of a project. |
