A new approach in the design of first lining steel rib

These movements have a direct effect on the tunnel stability and the design load of the lining system (Lunardi et al., 1994). Tunnel linings are structural systems installed during and/or after excavation to provide ground support, to maintain the tunnel opening, to limit the ground water inflow, to support


Design and construction of segmental tunnel lining are crucial steps for building a mechanical driven tunnel with a live span of 100 years or more. Since client, designer and contractor have different roles on a project and basically different points of view to the execution preferably clear and fair contractual arrangements should be worked out.

Ultimate Limit State Analysis of a Segmented Tunnel Lining

Ultimate Limit State Analysis of a Segmented Tunnel Lining Results of fullscale tests compared to finite element analysis Arjan Luttikholt Section Structural Engineering Concrete Structures Faculty of Civil Engineering and Geosciences Delft University of Technology Keywords: Segmented tunnel lining, experiments, numerical simulations,

ThreeDimensional Structural Analyses and Design of ...

Abstract. This paper deals with the structural analyses of the segmented tunnel lining using threedimensional finite element model. With this model it is possible to observed stresses and deformations which occur in concrete lining during the construction stage (assembling) and .


The design engineer should use Load and Resistance Factor Design (LRFD) method to design precast concrete tunnel segments for ultimate limit state (ULS) and serviceability limit state (SLS). ULS which is a state associated with the collapse or structural failure of tunnel linings is discussed in this section. The current practice in the tunnel

Design of Concrete Tunnel Linings for Fire Safety IABSE

design of concrete tunnel linings subjected to severe fire exposure. The distinguishing feature of tunnel fires is the possible rapid rise of the air temperature within few minutes. The factors that contribute to this phenomenon in combination with the fire duration and the fire spread along the longitudinal direction are cited.


DESIGN RECOMMENDATIONS FOR CONCRETE TUNNEL LININGSVOLUME II: SUMMARY OF RESEARCH AND PROPOSED RECOMMENDATIONS. The report presents design recommendations for concrete tunnel linings for transportation tunnels. The recommendations developed as a result of indepth analysis and model testing of the behavior of concrete tunnel linings.

Tunnel lining | Maccaferri Corporate

The final lining is a fundamental stage. The final lining is the most important stage in the construction of a tunnel. It represent the final reinforcement which determines the durability and structural strength of the underground works, as well as being the support for the service installations such as final ventilation, aeration and lighting.

Structural behaviour of concrete segmental lining tunnels ...

The deployment of engineering models and design methods divorced from the effect that mechanised shield tunnelling with tunnel boring machines (TBMs) has on concrete segmental linings (CSLs) can lead to either material waste or structural damage within the tunnel design life.


by hard rock. It was also double checked with available face mapping data during tunnel interventions. Based on geological data, mining method was implemented for excavation of CP. PLAXIS was carried out for the deformation and stability of temporary lining and STAAD was carried out for the analysis design of Permanent Lining.


tunnel case history, an evaluation is made of the current design practice by comparing it with the design approaches involving the three rock mass classification systems. It is concluded that the current design practice may lead to overdesign of support, and recommenda
