Resumo: The presence of voids under footings can significantly reduce the stability of the foundation and the superstructure above it. Estimating the bearing capacity of a footing with voids below it is a complex and challenging problem in geotechnical engineering. This study investigates the stability of centrally and eccentrically loaded surface footings supported by sand layers of variable thickness overlying clay layers, with circular voids below the center of the footing. Using the Plaxis finite element software, the influence of various parameters on the overall performance of the footing, including load eccentricity, void location, void size, and introducing geogrid reinforcement at the sand-clay interface are analyzed. The results show that increasing the void depth, add a thick layer of sand or introducing geogrid reinforcement can mitigate the impact of a void beneath a foundation.

Estimar la capacidad de carga de una cimentación con vacíos debajo de ella es un problema complejo y desafiante en la ingeniería geotécnica. Este estudio investiga la estabilidad de cimentaciones superficiales cargadas de forma central y excéntrica apoyadas en capas de arena de espesor variable sobre capas de arcilla, con vacíos circulares debajo del centro de la cimentación. Utilizando el software de elementos finitos Plaxis, se analiza la influencia de varios parámetros en el rendimiento general de la cimentación, incluyendo la excentricidad de la carga, la ubicación del vacío, el tamaño del vacío y la introducción de refuerzo de geogrilla en la interfaz arena-arcilla. Los resultados demuestran que el aumento de la profundidad del vacío, la adición de una capa gruesa de arena o la introducción de refuerzo de geogrilla pueden mitigar el impacto de un vacío debajo de una cimentación.Universidade Federal de Viçosa - UFV2024-04-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1750610.18540/jcecvl10iss3pp17506The Journal of Engineering and Exact Sciences; Vol. 10 No. 3 (2024); 17506The Journal of Engineering and Exact Sciences; Vol. 10 Núm. 3 (2024); 17506The Journal of Engineering and Exact Sciences; v. 10 n. 3 (2024); 175062527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/17506/9581Copyright (c) 2024 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNezari, AbdelhakimBoufarh, RafikMansouri, Tarek2024-05-15T20:25:07Zoai:ojs.periodicos.ufv.br:article/17506Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2024-05-15T20:25:07Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false
