A simulation of dynamic forces acting on invert prefabricates in TBM constructiontunnel is made with surrounding rock-structure model by using ANSYS software.
According to the special structure of precast block of inverted arch for TBM constructiontunnel, the dynamic construction state is modeled by FEM with surrounding rock - structure calculating model.
针对TBM施工隧道仰拱预制块的特殊结构，采用围岩-结构模式，进行了模拟施工动态的受力影响计算分析。
