| 摘要： | Based on the idea of typical strip method in higher concrete structure design,the joint detail structure of the concrete liner is solved by demixing firstly and then synthesizing.Meanwhile,the mechanical behavior of segment joint of shield tunnel is studied comparatively with the contact mechanics model of 3D FEM.It has been concluded that the typical strip method is a feasible method to calculate joint.Finite element method is proposed to be a major means of analysis,fitted and complemented with strip method.The flexural rigidity value range of segment joint of Shiziyang shield tunnel is probable 2.6 × 105 kN · m/Rad ～ 10 × 105 kN · m/Rad. |
