Abstract

Finite element model is performed to simulate the interactions between soils and concrete segments. A practical engineering example for double-layer linings of shield tunnel is numerically simulated with FEM in order to compute bending moment allocation ratio between bending moment on the initial lining segments and bending moment on the second concrete linings. Under the commonly designing thicknesses for double-layer linings of shield tunnel, with segment thickness h1=0.5m and second lining thickness h2=0.2m, the bending moment on initial lining segment burdens 97% of total moment on double-layer linings. So, the structural feature of the second lining concrete can be ignored.
