Control de asentamientos en diques sobre suelos blandos construidos en el proyecto control de inundaciones del Río Cañar

Abstract

This study aims to make a control of settlements that occur in the levees built in the "Control de inundaciones del Río Cañar" project, for which we calculate immediate settlements, primary and secondary settlements consolidation that will occur in the soil stratum on which the levees are settled and those calculated values are compared with results both made in surveying the field as with the project design values. We briefly described the processes needed to be followed to calculate the mentioned settlements as well as the procedures for constructing levees based in the technical specifications.Also discussed a topic rarely mentioned as subsidence or own settlement of the levee body. Before the settlements calculations, trial data that are involved in those calculations arecollected to establish the mechanical-geotechnical characteristics of each stratum, with this information proceeds to calculate the settlements with the help of a sheet Excel software. Topographic measurements were performed for five months by two surveying instruments: "Differential GPS" and "topographic level." Finally we exposed the conclusions and recommendations on the results of calculations, measurements and design values, and a projection of time on the levees will have the total settlements.
