Abstract
Esta memoria consiste, en realizar un estudio detallado de los principales
métodos de excavación. En los distintos túneles que se han hecho en el mundo.
En primera instancia se hace un enfoque en la construcción de las primeras
líneas de metro en la ciudad de Santiago, detallando métodos tales como: a tajo
abierto (cut and cover) y posteriores modificaciones con el uso de pilotes.
Posteriormente se describieron otros métodos para distintos tipos de suelo,
específicamente los compuestos por rocas, con toda su secuencia constructiva
al usar explosivos o maquinas rozadoras.
Se describen métodos con la utilización de maquinarias tuneleras (TBM) que las
hay tanto para uso en suelos blandos, como en suelos duros. Teniendo
aspectos positivos desde el punto de vista de plazos para ejecución de
proyectos completos, y de prevención de riesgos frente a otros métodos más
tradicionales.
Finalmente se detalla el método de excavación actual que tiene el Metro de
Santiago, con su procesos y secuencia constructiva.
Con la información obtenida de los métodos más tradicionales y utilizado en la
construcción de túneles, se realiza un cuadro comparativo destacando las
incidencias más importantes a comparar entre un método a otro. El análisis
comparativo finaliza con las conclusiones y recomendaciones respectivas de
toda la investigación realizada.
This study consists of an in-depth study of the main excavation methods for tunnels that have been made in different parts of the world. In the first instance, a focus is taken on the construction of the first Metro lines in Santiago, detailing methods such as: cut-cover and subsequent modifications with the use of piles. Later, other methods for different types of soil were described, specifically the compounds by rocks, with all its constructive sequence when using explosives or machines rubbing. Methods are described with the use of tunneling boring machines (TBM) that are available for soft and hard soils. Having plenty of positive aspects from the point of view of deadlines for execution of complete projects and prevention of risks compared to other traditional methods. Finally, the current method of excavation of Metro de Santiago is detailed, with its processes and construction sequence. With the information obtained from traditional methods and tunneling construction, it made a comparative table to know the main differences. The comparative analysis concludes with the respective conclusions and recommendations of all the research carried out.
