Study on the Parameterized Model for Tunnel Lining Structure Safety Analysis with APDL and UIDL

摘要

In tunnel engineering, the forms of lining structure usually are similar. In order to conveniently and quickly evaluate and analyze the tunnel lining structure safety, based on the general finite element software ANSYS, a parameterized model for tunnel lining structure safety analysis with APDL and UIDL was researched in this paper. The results show as follows: The developed parameterized model using the numerical method of limit analysis of strata structure may not only conveniently and quickly evaluate and analyze the tunnel lining structure safety, but also analyze and calculate the safety factor of tunnel lining structure taking into account the effect of tunnel excavation process. The applicability and simplicity of the developed parameterized model in the paper also support its usefulness.
