Resumo: | The peak particle velocities (PPV) are fundamental for understanding and managing the levels of blast-induced ground vibrations and their effects on adjacent structures. Given that numerical analysis of seismic vibrations has been demonstrated to be a method that can significantly contribute to predicting PPV, this study adopts a numerical approach using the finite element method (FEM) to assess blasting-induced ground vibration in rock masses. A dynamic module of the stress-strain analysis based on the FEM displacement formulation is developed in ANLOG software to estimate the variations of displacement, velocity, strain, and stress induced by blasting. The dynamic modulus implemented is verified using two verification examples. After, ANLOG is used in an application example to estimate seismic vibrations induced by blasting and to define the attenuation law for a limestone quarry near an urbanized area in Spain. The effect of Rayleigh damping coefficients (α and β) on the PPV levels estimated by ANLOG was investigated, and the most appropriate numerical attenuation law is then obtained. The numerical analysis presents satisfactory results for elastic-wave propagation induced by blasting and the peak particle velocity values obtained shows good agreement with field and the numerical results available in the specialized literature. The results indicate that ANLOG can perform personalized analysis of rock mass under blast-induced dynamic stress taking into consideration the geological and geomechanical characteristics particular to each medium as well as the blast parameters. |

Dado que el análisis numérico de vibraciones ha demostrado ser un método que puede contribuir significativamente a la predicción de VPP, este estudio adopta un enfoque numérico utilizando el método de elementos finitos (FEM) para evaluar las vibraciones inducidas por voladuras en macizos rocosos. Se desarrolló un módulo de análisis dinámico de tensión-deformación basado en la formulación de desplazamiento del FEM en el software ANLOG para estimar las variaciones en el desplazamiento, la velocidad, la deformación y las tensiones inducidas por la voladura. El módulo dinámico implementado se verificó utilizando dos ejemplos. Luego, se utilizó ANLOG para estimar los niveles de VPP y definir la ley de atenuación de una mina de piedra caliza cerca de un área urbanizada en España. Se investigó el efecto de los coeficientes de amortiguamiento de Rayleigh sobre los niveles de VPP estimados por ANLOG para obtener la ley de atenuación numérica más adecuada. El análisis numérico mostró resultados satisfactorios para la propagación de ondas sísmicas inducidas por voladura de roca y los niveles de VPP obtenidos muestran una buena concordancia con los resultados numéricos y de campo disponibles en la literatura. Los resultados indican que ANLOG puede realizar análisis personalizados del macizo rocoso bajo tensiones dinámicas inducidas por voladura de rocas, teniendo en cuenta las características particulares de cada medio y los parámetros de voladura.As velocidades de pico de partículas (VPP) são fundamentais para entender e gerenciar os níveis de vibrações sísmicas induzidas por desmontes de rochas e seus efeitos em estruturas adjacentes. Dado que a análise numérica de vibrações tem se mostrado como um método que pode contribuir significativamente para previsão dos níveis de VPP, este estudo adota uma abordagem numérica usando o método dos elementos finitos (MEF) para avaliar as vibrações induzidas por desmontes de rocha em maciços rochosos. Um módulo dinâmico de análise tensão-deformação baseado na formulação de deslocamento do MEF foi desenvolvido no software ANLOG para estimar as variações de deslocamento, velocidade, deformação e tensões induzidas pelo desmonte de rochas. O módulo dinâmico implementado foi verificado usando dois exemplos. Em seguida, o ANLOG foi usado na estimação dos níveis de VPP e na definição da lei de atenuação de uma pedreira de calcário próxima a uma área urbanizada na Espanha. O efeito dos coeficientes de amortecimento de Rayleigh nos níveis de VPP estimados pelo ANLOG foi investigado para obter a lei de atenuação numérica mais adequada. A análise numérica apresentou resultados satisfatórios para propagação de ondas sísmicas induzidas por desmonte de rochas e os níveis de VPP obtidos mostram boa concordância com resultados de campo e numéricos disponíveis na literatura. Os resultados indicam que o ANLOG pode realizar análises personalizadas de maciço rochoso sob tensão dinâmica induzida por desmonte de rochas, levando em consideração as características geológicas e geomecânicas particulares de cada meio e os parâmetros de desmonte.Research, Society and Development2022-10-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3542110.33448/rsd-v11i13.35421Research, Society and Development; Vol. 11 No. 13; e205111335421Research, Society and Development; Vol. 11 Núm. 13; e205111335421Research, Society and Development; v. 11 n. 13; e2051113354212525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/35421/29628Copyright (c) 2022 Caroline Belisário Zorzal; Christianne de Lyra Nogueira; Hernani Mota de Limahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessZorzal, Caroline Belisário Nogueira, Christianne de LyraLima, Hernani Mota de 2022-10-17T13:43:46Zoai:ojs.pkp.sfu.ca:article/35421Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:50:20.937839Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
