Shape optimisation of the support section of a tunnel at great depths 作者:Lu, AZ (Lu, A. Z.)[ 1 ] ; Chen, HY (Chen, H. Y.)[ 1 ] ; Qin, Y (Qin, Y.)[ 1 ] ; Zhang, N (Zhang, N.)[ 1 ] COMPUTERS AND GEOTECHNICS 卷: 61 頁: 190-197 DOI: 10.1016/j.compgeo.2014.05.011 出版年: SEP 2014 查看期刊信息 摘要 The shape optimisation of a cavity is typically performed without considering the previous support, which may significantly reduce the practical significance of such analyses. Even when an excavation section is optimised, failure of the surrounding rock in a tunnel cannot be prevented in the presence of excessive in situ stress. Thus, a support should be established to protect the stability of a tunnel from the failure of the surrounding rock. This study examines the optimal shape of the support that satisfies the optimisation criterion, which minimises the largest tangential stress along the inner edge of the support, for a specific net tunnel size and support strength. The optimisation process is to solve a series of forward problems using the conformal mapping method for a plane elasticity complex function. The tangential stress along the inner edge of the support is selected as the objective function, and the coefficients of the mapping function are considered as the design variables. The minimum value of the objective function is calculated based on the mixed penalty function method and the optimal support shape that satisfies the given constraints can be obtained. The stress state of an optimally shaped tunnel support is significantly improved compared to non-optimal configurations, and the stress concentration along the inner edge of the support is minimised.

Box 447, Leiden, 2300 AK, Netherlands Abstract: Based on the plane elastic complex function method, theoretical analysis on the stress field around a circular tunnel with ring lining subjected to in situ stresses and inner hydrostatic pressure is carried out. The results of two extreme boundary conditions cases, pure slip and pure bond, are compared with each other. The displacement release coefficient is considered. The calculation results show that the magnitude of the deformation completed before lining installation has great effects on the stress distribution in the lining. If the lining is installed at a proper moment, the degree of stress concentration in the lining can be minimized. When theYoung's modulus of the lining is much lower than that of the rock, stress solutions for two extreme boundary condition cases are roughly the same. The smaller the lateral pressure coefficient λ, the larger the differences between the corresponding stress solutions for two extreme boundary condition cases. © 2014 Taylor & Francis Group, London.
