3D simulation of tunnel excavation in soft soil

Abstract

In this study, an analysis of the deformations and the stability of tunnel face in soft soil using several calculation procedures aimed at making confrontations are presented. Our purposes to approach three-dimensional modelling in tunnelling by a series of 2D computations using three procedures: The Lost Volume method (LVM), the Convergence Confinement method (CCM) and the face pressure method (Pf). A series of numerical studies was carried out to estimate the settlements, longitudinal and horizontal displacements. Analytical and empirical approaches have also been used to make comparisons. The results showed the interest of such analysis. The comparison of the numerical results to those calculated with different methods shows good agreement.
