Stability analysis and safety monitoring on anchorage foundation with building envelope of diaphragm wall

Based on the north anchorage foundation of Runyang Bridge, some beneficial results were obtained concerning the stability of Anchorage foundation. The finite element method shows great advantage to analysis the nonlinear problem concerning the anchorage foundation stability, which can raise the efficiency and calculation accuracy greatly. The safety monitor model, based on the output of three-dimension finite element simulation, is reasonable. The dynamic prediction analyses based on the monitoring data ensured the stability and safety of the anchorage foundation.
