Análise e desenvolvimento de projeto construtivo de uma pequena barragem de terra no Córrego da Cava – Morrinhos/GO, com foco na segurança

Abstract

The dams are civil works of great importance in the management of water resources, since they store water in the rainy season to meet demands during periods of scarcity. The existence of small earth dams is very common and most of the time they are built without the elaboration of project, putting at risk the work and the people and causing financial losses. In Goiás such practice is common, a fact related to occurrences of rupture of dams with significant damages. The constructive design of earth dams should be done by trained professionals, based on studies, analyzes and appropriate criteria. The objective of this work was to develop and analyze the constructive project of a small earth dam in the Cava Stream, in Morrinhos / GO. The project was developed from the detailed steps of choosing the location of the dams, surveying, hydrological studies and hydraulic and structural design of the dam itself. At the end, the project was submitted to simulation of stability of the land mass through the program Geostudio 2016 - SLOPE / W, considering the dimensions of calculation and assignment of expected values to the parameters of analysis. The results obtained were satisfactory for the simulated conditions, referring to the adequate stability of the earth mass of the projected dam.
