Analysis And Test For Lining Whole Wreath Of Shanghai-Chongming Tunnel

The tunnel engineering of Shanghai—Chongming is Shanghai or one of the national important foundation facilities developments engineering, designs basis period as 100 years and adopts shield tunneling method to construct it. The tunnel's diameter is 15.0 m; and then; it will be the biggest tunnel in the world. For verifying the tunnel lining loading ability and stability, holding the whole wreath to carry loading and transformation, it's necessary to precede the tunnel lining 1:1 whole wreath experiment. As a result, this paper aims at those problems to do research work, as follow several aspects:This paper introduces the static tests of a full-scale shield-tunnel lining with staggered-joints in detail, which was done in the Wu Haogou.Pudong. Shanghai at February to April in 2006. And then, gathering data under six testing load cases is processed to deduce the important parameters of the lining design. Then, it precedes the analysis of inside transformation result, discussing the different analysis method and experimenting method to produce error result. At the end of this paper, finite-element computational software — ANSYS — is used to the numerical analysis of shield-tunnel lining. The bolts and interactive forces at the staggered-joints are simulated in the model of FEA, in which the nonlinear contact element is also considered to reach the instructional suggestions to the design.
