| 摘 要： | 结合地铁盾构隧道工程实例，应用三维有限元模型和ANSYS程序分析了上部和周围土体荷载作用下钢筋混凝土衬砌的应力、应变分布与开裂规律。模型考虑了衬砌与周围土体的共同作用、土体和钢筋混凝土材料的弹塑性性质，通过刚度折减考虑了管片接头不连续性对衬砌应力、应变与开裂性质的影响。

| Abstract: | Connectiong to the actual shield tunneling construction of metro, the paper tends to use 3D finite element model and ANSYS code to analyze the stess and strain distributions and crack rule of RC shield tunnel lining. By taking the soil around the tunnel as a part of the FE numerical model, the interaction between lining and soils as well as the elastoplasticity of soils and steel reinforced concrete were considered in this model. The rigidity reduction model of the segment joint was put forward in the paper and the influence of the segment joint to the stress, strain and crack rule of tunnel lining was quantitatively analyzed as well. |
