摘要：

根据Saenz公式将混凝土本构模型简化为双折线线性强化弹塑性模型，推导了混凝土弹塑性参数的计算公式．应用大型结构分析有限元软件Algor对装配式管片接头进行三维线弹性和弹塑性有限元分析，得到了混凝土应变、接头位移、接缝转角、螺栓拉力等计算结果，并将有限元计算结果与接头荷载试验测试结果进行了对比．研究表明，有限元计算值与试验值两者的变化规律是一致的，计算结果在反映结构应力／应变分布规律方面有重要参考作用．

Abstract:

The double lines strengthening elastic-plastic model was developed by simplifying the concrete constitutive law according to Saenz formula. The formulae for the model parameters were given. The structural analysis procedure Algor was taken to conduct the linear elastic and elastic-plastic FEM analysis on the joints of segments. The strain distribution of segment, the displacement of joints, the rotary angle of joints and the tensile force of joint bolts were given. The comparison between FEM calculation and test results was made, which shows that the finite element analysis results correspond with the test results. The FEM analysis results can bean effective measure to observe the distribution patterns of the strain and stress.

Key words: loading test, constitutive model, shield tunnel, finite element analysis
