Abstract: In this paper, a three-dimensional nonlinear FEM model of RC shield tunneling lining is proposed to deal with the simulation of Guangzhou Underground Line 3. The nonlinear FEM code ANSYS is used to analyze the stress and strain behavior of lining structure which is subjected to the covered soil and the applied surface loads. Three-dimensional solid elements are adopted in this numerical model. The interaction of lining and around soil, the nonlinear properties of concrete and soil is considered. The influence of the segment joints on the stress, strain and crack properties of lining is discussed allowing for the reduction of joint rigidity. A series of physical model tests were designed to verify the numerical solutions to the lining structure. The stress, strain, structural displacements and crack distribution are illustrated in this paper.
