针对盾构隧道的施工阶段、注浆材料及管片接头的特性提出了有限元模拟方法。在有限元分析中考虑了盾构衬砌接头的转动效应和盾尾部位注浆材料在施工中由液态向固态转化的凝固过程，并采用作者提出的梁-接头不连续模型与注浆材料的变刚度等效法来模拟其力学变化。将建立的施工模拟有限元软件应用于大阪地铁7号线盾构隧道施工的力学分析中，并对在均市和非均布注浆压力下，土压力及衬砌内力的计算值与实测值作了比较分析，发现非均布条件下的计算值较均布条件下的计算值接近于实测值。
According to the characteristics of the grouting material and the joints of the shield tunnel, the finite element simulation method is proposed. In the finite element analysis, the rotating effect of the shield lining joints and the solidification process of the grouting material at the tail of the shield from liquid to solid state during construction are considered. The discontinuous beam-joint model and the grouting material Stiffness equivalent method to simulate the mechanical changes. The construction simulation finite element software was applied to the mechanical analysis of shield tunnel construction of No.7 Metro Line in Osaka City. The calculated and measured values of earth pressure and lining internal force under urban and non-uniform grouting pressure A comparative analysis shows that the calculated values under non-uniform conditions are closer to the measured values than those under uniform conditions.
