- Abstract
Based on ihe open system of finite element analysis software SiPESC. FEMS and its elasto-plastic analysis framework, a new finite element analysis algorithm framework for the tunnel construction is realized with the commonly used stratum structure model theory and related technologies. In this framework- the initial stress of the surrounding rock is calculated by geoslatic equilibrium analysis. The loading and unloading process required in multi-step analysis for cruslal stress balancing is implemented by using elasto-plastic analysis in SiPKSC. FEMS. The technology of birth-death element is realized benefiting from the flexible management of elements and properties in SiPKSC. FEMS. The technology of embedded element is achieved by the employment of multipoint constraint method in SiPKSC. FEMS. The task flow of multi-step analysis in tunnel construction is constructed by the configuration of dynamic task flow from SiPESC. FKMS. Numerical examples show that the new framework is suitable for the numerical simulation of tunnel construction process and il can be used to calculate the stress change in the process of crustal stress balancing effectively and to obtain the optimal tunnel construction scheme.
