ANALYSIS OF GROUNDWATER LOWERING TECHNIQUES APPLIED TO SEDIMENTARY SOILS

Abstract

The lowering of the water table is a system that aims to allow the displacement of groundwater contained in the area designed for the construction of engineering works. It is worth pointing out that this theme is broad as to the means of execution, basing itself mainly on theoretical foundations and, at the same time, is scarce in technical information obtained in loco. The employability of groundwater lowering systems considers several factors, especially the soil-water correlation, demonstrating the importance of an accurate study of the geological profile and the type of work to be executed, since inadequate drainage can generate pathologies, the result of which can cause future problems, both in the work and in its surroundings. The present paper aims to evaluate two techniques for lowering the water table, filtering point and deep wells, in a stratigraphic profile of sedimentary soils applied during the excavations of a building complex, analyzing from the sizing of the chosen methodologies a comparison through costs and technical feasibility, demonstrating the employability of the filtering point system according to the geological and geotechnical characteristics of the site.
