La gestión de inmuebles históricos encuentra problemáticas específicas en el caso del patrimonio fortificado que se localiza en contextos urbanos: demoliciones, afecciones arqueológicas, deterioro, etc. Dichas cuestiones se ejemplifican en el caso de la muralla medieval de Sevilla, construida prevalentemente en tierra mediante la técnica del tapial. Estas entidades, de gran extensión y elevada complejidad, resultan idóneas para el empleo de sistemas de información geográfica (SIG). La gestión cartográfica digital (GCD) aboga por el uso de modelos simplificados que permiten alcanzar la definición de la escala arquitectónica, facilitando el posterior uso de herramientas tridimensionales. La transversalidad que exige la construcción de una base de datos destinada a la conservación preventiva, y su componente multiescalar, requieren de un importante proceso de normalización que debe abarcar sus componentes terminológica, temática y espacial. El presente artículo comparte los resultados alcanzados en esta fase del proceso, atendiendo a la caracterización básica de aquellos elementos identificados en el sector de la Macarena.

Institutions such as ICOFORT (International committee on fortifications and military heritage) encourages the development of diagnosis strategies for the conservation and maintenance of historic earthen walls as highly necessary. Thus, it is important to be aware of the conditions in urban contexts, where the deterioration can be more aggressive and the risk of damage increases. Despite this, there are many strategies of constructive diagnosis for these kinds of monuments, but not many of them are concerned with the structural assessment of situations in which the ramparts work as a retaining wall in an unforeseen way. The medieval ramparts of Seville (Spain) are shown as a completely representative case study of the above-mentioned situation. In the research sector, the monument resists the lateral earth pressure developed by the new difference in height at both sides of the wall. Based on the limited states principle and on different international codes formulation, a tool was programmed to carry out automatic calculations to verify the case study’s overall stability conditions using standard sections. The obtained results were based on the overturning, bearing, and sliding overdesign factors (ODF) and determined a stable situation that could be at risk because of changes in the surrounding such as, excavations or the movements of the ground water table, or seismic events. Thus, the need and usefulness of strategies and control instruments that should be integrated into heritage intervention projects have been proved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
