Summary
The aim of this paper is the study of the pathology observed in Baldornon's church, Spain and a scheme for the restoration procedure based on the finite element calculation. The pathology is due to a lack of stiffness of the church's soil, giving rise to important damage: cracks in the walls, cracks on the floor, loss of tightness (watertight integrity) and finally, the collapse of the structure can take place.

Therefore the study of the consolidation of the monument and its structural stability constitutes a matter of great theoretical and practical interest, and it requires an evaluation and some specific knowledge, intimately associated with the resistance of materials and the numerical modelling [1,2]. It is very important because this work contributes to the architectural restoration by means of the relationship between the structural stability and the modern numerical techniques in the study of the soil-structure interaction [3].

In this paper, we propose a practical solution for this problem based on the non-linear coupled analysis of the soil and the concrete reinforced structure using the finite element method. The solution is to strengthen the previous existing rock-filling wall by means of a gunited concrete and counterforts with concrete anchorages inside the soil, crossing laterally the church by both sides. Finally, the conclusions of this study are explained.
