Estimation of the dry density of a granular backfill using the dynamic cone penetrometer

The quality control of a fill is generally performed with standardized methods, such as the sand cone and the nuclear densimeter, but an alternative method, the dynamic cone penetrometer, is being proposed and is usually used to calculate the in situ California bearing ratio. In this investigation,...

In this investigation, the dynamic cone penetrometer was used to perform quality control of a silty clayey gravel soil with sand. First, the material was characterized, basic and specific tests were carried out, and a 12,00m long test fill was made, divided into seven zones, compacted with different energies, and sand cone and dynamic cone penetrometer tests were carried out. With the data obtained, a correlation equation was determined, where the dynamic cone penetrometer index was the independent variable and the dry density the dependent variable. With the equation we proceeded to calculate the dry density of a compacted platform with a single test energy of 2,40x2,40m, a good correlation was estimated between the compacted dry density and the dynamic cone penetrometer index, thus showing the possibility of its use in the quality control of a granular backfill. In the comparison of the dry density calculated from the correlation equation and the density found with the sand cone, it was observed that it varies around 6% El control de calidad de un relleno generalmente se realiza con métodos estandarizados, como el cono de arena y el densímetro nuclear, pero se viene planteando un método alternativo, el penetrómetro dinámico de cono, que usualmente se utiliza para calcular la relación de soporte de California in situ. En esta investigación se utilizó el penetrómetro dinámico de cono para efectuar el control de calidad de un suelo de grava limosa arcillosa con arena. Primeramente se caracterizó el material, se realizaron los ensayos básicos y específicos, por otro parte, se realizó un relleno de prueba de 12,00m de longitud dividida en siete zonas, compactados con diferentes energías, realizándose pruebas de cono de arena y penetrómetro dinámico de cono. Con los datos obtenidos se determinó una ecuación de correlación, donde, el índice de penetrómetro dinámico de cono fue la variable independiente y la densidad seca la variable dependiente. Con la ecuación se procedió a calcular de densidad seca de una plataforma compactada con una sola energía de prueba de 2,40x2,40m, se estimó una buena correlación entre la densidad seca compactada e índice de penetrómetro dinámico de cono, mostrando así la posibilidad de su uso en el control de calidad de un relleno granular. En la comparación de la densidad seca calculada a partir de la ecuación de correlación, y la densidad hallada con el cono de arena se observó que varía alrededor de un 6% Universidad Centroccidental Lisandro Alvarado - Decanato de Ingeniería Civil 2023-07-24 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo científico de investigación original application/pdf https://revistas.uclave.org/index.php/gt/article/view/4514 10.51372/gacetatecnica242.6 Gaceta Técnica; Vol. 24 No. 2 (2023): July-December; 77-91 Gaceta Técnica; Vol. 24 Núm. 2 (2023): Julio-Diciembre; 77-91 Gaceta Técnica; v. 24 n. 2 (2023): July-December; 77-91 2477-9539 spa https://revistas.uclave.org/index.php/gt/article/view/4514/2879 Copyright (c) 2023 Iván José Guevara Lopez, Ferrer Canaza Rojas https://creativecommons.org/licenses/by-nc-sa/4.0
