El movimiento en la ejecución de recalces con inyección armada. Análisis de tres casos con movimientos previos

Abstract

We can produce movements in a structure when we have an intervention in its foundation. This movement is higher if the building has a previous movement if it is cause for degree and pathologic causes. In this paper we study the results of the analysis in the application of a technique of intervention in the foundation of an existing building. The technique for underpinning is by reinforced grouting. We present three histories cases over buildings that have previously differential settlements of pathological origin for a prolonged period of time. Its underpinning was with this technique. The study is based on knowledge of the movements are obtained by controlling the application of underpinning of each of the three examples. We have unified the criteria used for analysis to compare the results. The main conclusion is that the 3 buildings used in the study respond similarly to the actions executed. Therefore, we consider this behaviour as the normal response of the soil in these cases.
