After discussing existing methods of constructionsimulation, an ameliorated analysis method of cycle-forward is developed, which is based on the method of cycle-forward and ANSYS software.
A simulation of dynamic forces acting on invert prefabricates in TBM construction tunnel is made with surrounding rock-structure model by using ANSYS software.
According to the system models talked above, the system simulationsoftware for the construction of underground structure group is developed using the object-oriented technology.
