| 英文摘要 | Abstract Recent tunnel shape optimization considers only the stress distribution in the soil around the tunnel or the lining’s mechanical performance and frequently ignores the influence of the interaction between the lining and soil. Thus, this study presents a tunnel shape optimization method considering this interaction. First, the concept of a lining rational arch axis is employed to derive an analytical expression for the tunnel shape, which is subjected to earth pressure recommended by the International Tunneling Association (ITA). Further, the rationality of the obtained tunnel shape is verified using a finite element method (FEM) simulation, which considers the interaction between the lining and soil. Thus, an iterative FEM is further proposed to minimize the lining’s eccentricity. The tunnel shape is gradually modified via the iterative FEM by offsetting the lining axis along the normal vector using the corresponding eccentricity to obtain the optimal tunnel shape. The results reveal that, with the optimal tunnel shape based on the rational arch axis, the tunnel lining is mainly subjected to axial compressive force and exhibits good performance in terms of deformation and bending moment. |
