THE PREDICTION AND THE CONTROL OF DISPLACEMENTS AROUND DEEP EXCAVATIONS IN COMPLETELY DECOMPOSED GRANITE

PREVISION ET CONTROLE DES DEFORMATIONS AUTOUR D'UNE FOUILLE PROFONDE DANS LE GRANITE COMPLETEMENT DECOMPOSE

This paper covers two subjects: the construction methods employed in Hong Kong to keep displacements around deep excavations to a minimum and the prediction of displacements using small strain models. Of importance for the prediction of displacements, it is shown that completely decomposed granite of the Kowloon Pluton exhibits small strain stiffness behaviour typical of sedimentary soils. In the case history presented, finite element computations with a small strain stiffness model gave good predictions for lateral wall displacement but the vertical settlement predictions were less good, possibly due to the effect of remnant structure in the completely decomposed granite not allowed for in the model.
