【Abstract】 The nonlinear three-dimensional finite element analysis of the 50m deep excavation support during the foundation construction of the north anchor in the Runyang Yangtze River Bridge project has been carried out and discussed. After a brief description of the relevant facts, the numerical model and the input parameters are proposed. Calculations are performed considering various influence factors. Based on the analyses the feasibility of the support system design is evaluated. The outcome of the execution proved the proceeding evaluations.更多还原
