Delivery time: 8-12 business days (International)
Durante los setenta ltimos aos del pasado siglo XX, puede decirse que tuvo lugar uno de los periodos de mayor impulso y desarrollo de la ingeniera civil en la ms reciente historia de Espaa. Analizando con cierto detenimiento las obras civiles espaolas que a lo largo de esos aos han tenido sntomas de algn tipo de patologa especfica, problemtica o complicacin, es notorio comprobar que muchos de ellos se solucionaron de forma sorda. Esto es, sin saber muy bien qu haba pasado realmente y dnde se encontraba el origen del fallo, accidente o la causa que lo desencadenaba. Esta causa se relacionaba con las condiciones geolgicas pero no se profundizaba en el conocimiento cientfico de los problemas. Dentro de este cmulo de dificultades son de destacar los ocurridos en las cimentaciones de diversas estructuras y obras de sostenimiento de tneles durante el proceso de excavacin, ejecutadas todas ellas en facies arcsicas o arcosas propiamente dichas. Con el trabajo se pretende entender el origen de los problemas desde los puntos de vista geolgico y geotcnico y desarrollar nuevas tcnicas de ensayo que permitan calibrar su peligrosidad.
