Summary
This paper presents a brief geological and geotechnical description along the admission system, as well the executives methods and results of connection, consolidation and prestressing grouting, and also the obtained control data relative to the prestressing effect in the concrete lining.
The authors emphasize the efficiency of the treatment performed, notwithstanding the fact that the rock masses considered are from slightly to moderately jointed and pervious.
Resume
Cette communication présente un aperçu succinct de la géologie des galeries en charge, aussi bien que les travaux d’injection de collage, consolidation du rocher et pré-contrainte du revêtement en béton.
Les mesures de contrôle des effets de la pré-contrainte du revêtement montrent que la méthode adoptée a été efficace même quand’il s’agit d’un massif rocheux moyennement à faiblement fissuré et perméable.
