| Abstract: | Take great Bridge high pier of Yesanhe for example, this paper analysed the high piers euler and extreme value stability. The calculation results showed that, the influence of calculation model and geometry characteristics of structure to its stability was bigger, bridge pier ratio of slope and the label of bridge pier concrete was also the major factor to influence the stability of high piers extreme value. |
