Abstract Due to the large number of finite element mesh generated, it is difficult to use full-scale model to simulate largesection underground engineering, especially considering the coupling effect. A regional model is attempted to
achieve this simulation. A variable boundary condition method for hybrid regional model is proposed to realize
the numerical simulation of large-section tunnel construction. Accordingly, the balance of initial ground stress
under asymmetric boundary conditions achieves by applying boundary conditions step by step with secondary
development of Dynaflow scripts, which is the key issue of variable boundary condition method implementation. In
this paper, Gongbei tunnel based on hybrid… More >
