The Dynamic Construction Numerical Analysis of Large-Span Section, Long and Deep-Depth Tunnel

Abstract:

Using finite element principle, the numerical simulation analysis model of the tunnels with large-span, long and deep-depth was established. The killed cells excavated in part as, while supporting part as a unit was reactivated among the simulation analysis. The changing characteristics of the initial stress field, the circular soil excavation and supporting, the core soil excavation, as well as the down step excavation and supporting was simulated analysis during dynamic construction of the tunnel. Those will be provided a scientific basis for the safe construction.
