Abstract
El colapso ocurrido el 10 de noviembre de 2003 y que produjo el
posterior derribo de la Casa Azul de Calatayud fue objeto de estudios
encaminados a la identificación de la extensión de la cavidad original
que lo originó, la búsqueda de soluciones que permitieran la estabilización
del edificio, y la evaluación de los factores precondicionantes y
detonantes del evento ocurrido. La revisión de dicha documentación,
años después, permite realizar algunas consideraciones sobre la representatividad,
significado y resultados obtenidos en dicho momento
e inferir conclusiones para el desarrollo urbano futuro de la zona.
Los resultados permiten identificar la contribución de la actividad
paleokárstica en la pérdida de compacidad del material transicional
substrato-cuaternario, la afección posterior a los materiales recientes
localizados en su vertical y la extensión y origen del evento kárstico
posterior que afecta a la serie previa de la zona. La amplia densidad de
datos en la zona permite también realizar una evaluación de la representatividad
de los resultados obtenidos por aproximaciones discretas
y el interés de la retroalimentación entre ellos para definir campañas
de caracterización geológico-geotécnica-geofísica en contextos de
baja resistencia con procesos asociados de karst actual
A sinkhole collapse on November 10th 2003 affected the Casa Azul from Calatayud, which produced the later building tear down. Many analyses were carried out to identify the affected area, to look for potential solutions and to evaluate the conditioning and triggering collapse factors. Documentation review, years later, can permit to get some considerations about the representativeness, meaning and obtained results in such moment and to infer conclusions about the potential future urban development of the area. These results permit to identify the contribution from paleokarstic activity reducing the materials compactness in the units located between the substratum and the Quaternary, the later affection to such materials of karst processes and the size and extension of the karstic collapse that affected the analyzed area. The high density of different types of research approaches can permit to evaluate the representativeness of the obtained results from different discrete essays and the interest of the feedback evaluation of such data to define survey campaigns for the geological-geotechnical-geophysical characterization in similar contexts where low resistance materials exist and are affected by current karst activity
