ABSTRACT: The construction of the Bow office tower involved an excavation approximately 100 m wide, 190 m long, and about 21 m below ground surface. This paper presents a finite element analysis of stress and displacement caused by the excavation, and then evaluates the influence of the shear band and the weak zone in rock by comparing the measured performance of the shoring system with the calculated.
RÉSUMÉ: La construction de la tour à bureaux Bow a nécessité une excavation d'environ 100 m de large, 190 m de long, et d'environ 21 m de profondeur. Cet article présente les résultats d'une modélisation numérique par la méthode des éléments finis du champ de contraintes et de la quantité de déplacement induits par l'excavation. Par la suite, l'influence des différentes valeurs de cisaillement et la zone de faiblesse dans le roc ont été évaluées en comparant les performances mesurées du coffrage avec les valeurs calculées.
