Abstract Although soil-lining interaction is highly dependent on the employed tunnelling technology, most of the available design methods of tunnel linings fail to take into consideration such important factor. During tunnel excavation, the in-situ stresses are significantly altered depending on the tunnelling technique as well as the configuration of tunnel and the characteristics of the soil deposits. These reduced stresses are the starting point of the soil-lining interaction with lining activation. This thesis presents a method of lining design considering the details of the excavation procedure and lining installation. Interaction between the tunnel lining and the ground is analysed in two stages namely; excavation and interaction. The excavation stage is responsible for determining the pre-lining soil deformations and the reduced in-situ stresses. The interaction stage models the soil-lining system together. Soil continuum, tunnel lining, and the interface between them are idealized in the whole system using nonlinear finite element techniques. The deformations of the soil-lining system, as well as the lining internal forces, and equilibrium soil pressures are determined. Furthermore, results of the proposed analytical method as well as commonly used procedures are compared with field measurements compiled during the construction of several tunnel projects. These projects represent differet tunnelling techno10~ies, different lining systems, different tunnel configurations, and different soil deposits. The results indicate the large deviation between the common used lining design procedures and the actual lining behaviour. |
