| Abstract: | The stability is very important for the design and construction of long span continuous rigid frame bridge with high pier. Taking Liziping Bridge as an example and based on Euler elastic theory, the three-dimen- sional stability is calculated by finite element method. Finally the method of stability analysis of such type bridge is suggested by analysis and comparison in this paper. |
