通过通用有限元程序Ansys对天津地铁盾构隧道管片接头进行建模。研究了管片接头的转角与弯矩的关系，并用拟合法求出了管片接头的抗弯刚度值。此外，还讨论了偏心距对抗弯刚度的影响规律。
Through the general finite element program ANSYS to model the segment joints of Tianjin Metro shield tunnel. The relation between rotational angle and bending moment of a segment joint were investigated, and the numerical value of flexural rigidity is obtained by fitting method. In addition, the varying law of flexural rigidity is influenced by eccentricity is discussed.
