    Proceso de ASC - CARACTERIZACION MECANICA DE LOS RESIDUOS MINEROS Y EVALUACION DE LA SUSCEPTIBILIDAD A LA LICUACION ESTATICA Y DINAMICA DE LAS PRESAS DE RELAVES MINEROS DE BURITICA Y CERRO MATOSO.

    In mining projects, around 50 thousand tons of rock are extracted per day, where each ton, 5 grams or less of gold are obtained, the remainder is known as tailings. These waste are stored in more than 18,000 tailings dams in the world with a capacity of around 200 million tons each (Lyu et al., 2019). It is important to mention that throughout history, serious accidents have occurred due to the failure of these structures, since there are 6 to 14 times more likely to fail than water reservoirs (Emerman, 2018). Since tailings are loose and saturated, they are susceptible to liquefaction. The objective of this project is to understand how liquefaction works in these materials, through field visits, the characterization of behavior in the laboratory and, finally, improve the vibrating table to visualize liquefaction in these soils. The results of this project have been disseminated to through the social networks of the seedbed on Instagram as a product of citizen participation, A technical day on mining tailings was also organized at the EAFIT University with the support of the specialization in Soil and Foundation Mechanics and the company SRK. Also I know will present a dissemination article in the Social Appropriation of Knowledge (WP) format. These results raise awareness in the academic community and society about mining tailings and the importance of research to mitigate future disasters in the industry.

    In modern engineering, the difficulties presented by climate change and the growing global population have increased the demand for adaptable, sustainable, robust, and multifunctional infrastructure. This is especially important in geotechnical engineering. In this field, designing underground structures that can support structural loads is the fundamental goal. Structural optimization of foundations is a critical component in realizing sustainable constructions. An innovative approach incorporates Nature-inspired designs, translating biological principles into the geotechnical context to offer novel solutions. To design bio-inspired solutions, we evaluate their potential improvements by considering the differences between the demands and mechanical conditions of biological and engineering materials and systems. For this purpose, we developed a BESO algorithm that optimizes a root-inspired foundation. This marks the beginning of a deeper exploration into bio-inspired solutions for geotechnical problems, which underscores the necessity for a framework facilitating the implementation of Finite Element algorithms for structural optimization simulations of foundations. Such a framework enables the extraction and adaptation of a broader variety of materials, mechanisms, and designs from Nature. Finally, the combination of structural optimization and bio-inspired design can lead to a new paradigm in the design and construction of geostructures.
