| Abstract: | The mechanical behavior of double composite linings of the Yellow-River-Crossing tunnel is analyzed by using 3-D non-linear finite element method when contacts between assembled segments of outer linings,and contacts between the inner and outer linings are considered.The above numerical calculation is compared with the 1:1 simulation test of two models with and without cushions between the inner and outer linings.The test process,inclusive of the segments assembling,layered earth filling,pretensioning of in... |
