ABSTRACT
In general available design models and guidelines for the lining design of shield driven tunnels in soft soils do not explicitly involve the analysis of the assembling stage. Mostly, the basic assumptions require a non-governing assembling stage. Recent researches show the complex behaviour of the segmented lining during the assembling stage and they therefore draw recommendations to involve the assembling stage in the design process. This paper shows results and conclusions from the Ph.D. study at the Delft University of Technology: “Design philosophy of segmented linings for tunnels in soft soils”. This study provides extended insight in the structural behaviour of the lining during the serviceability and the assembling stage, by use of new analytical theories and analyses of the assembling stage.
