Abstract

In heavily settled areas, deformations i nduced by the tunnel excavation may cause serious damage to nearby structures. Theref ore, it is necessary to study effective means of controlling tunnel induced deformations. Th e main parameters affecting the failure and deformation state of the soil around a circular underground opening are the physical characteristics of the soil, the diameter of the opening, and the support pressure. In this study, 3-Dimensional (3D) FDM analyses were conducted to assess tunneling induced deformations, along with movements around Necatibey Station of K ızılay-Çayyolu metro line (Ankara, Turkey). During sequen tial excavations, temporary and permanent shotcrete lining was also simulated. The soil behavior is assumed to be governed by an elastic-perfectly plastic constitutive relation based on the Mohr–Coul omb criterion. The computed deformations around these openings have been compared with the in-situ measurements. The results of the study reveal ed that the 3-D elasto-plastic analyses yield comparably good correlation with the in-situ measurements.
