| Abstract: | The paper points out the optimal arch bridge’s arch axis can be achieved by the iterative calculation of the finite element method by identifying the design variables,the state variable,and the optimal principle,and proves the calculating method can improve the stress status of the arch in a better way by taking some engineering examples. |
