In the rapidly emerging Yunnan-Guizhou-Sichuan region, high-pier and long-span bridges are mostly high-pier and long-span continuous rigid-frame bridges over 100 meters, and the stability of their high-piers becomes more and more important. In order to study the stability of the structure under the action of pile-soil, the Wugong Bridge in Guizhou was used as a supporting project, and a large-scale finite element software was used to establish a construction model considering the effect of pile-soil. The influence of this type of bridge on the linear elastic stability of the structure under the action of pile-soil and the geometric nonlinear stability after considering the deflection of the structure is compared and analyzed.
