Métodos de controle de fluxo subterrâneo em estruturadas enterradas

Abstract

In buried earthworks, it becomes essential the need for knowledge of the implantation site, consequently the doing of geotechnical studies with the objective of obtaining soil parameters. Among these, the groundwater level is one of the most relevant, with direct impact in the construction. With groundwater at a high level, a point of detriment of the execution, it becomes necessary to control the percolation of water, through solutions with the capacity to stop this flow, to the extent that it intercepts the percolation that emerges on the slopes or at the bottom of excavations. The traditional methods used in engineering are divided into two large groups, based on how the underground flow is controlled, being basically the first by the principle of interruption and removal of the present water, already the other group is characterized by control through the construction of physical barriers with stone to exclude the flow from the area to be worked on. The present work studies the most traditional methods used to control percolation in buried structures, through a systematic review carried out through the study of literature and databases of scientific articles, both national and international. It is concluded that there is a need for a complex technical study with analysis of the evaluation of the scenarios for each project and the peculiarities of the soil to be explored, for the most technically and economically viable choice of the underground flow control system.
