| Abstract: | Longtan River Bridge is designed as a continuous rigid-frame bridge with its highest pier up to 178 m.In order to analyze the force influence of the bridge pier and the pile foundation on the bridge structure,this article establishes two different computation models of considering pile foundation action and with fixity at the base of pier,analyzing and comparing the box beam construction camber and the bending moments of structure control sections under temperature loading of both models. |

| Keywords: | the continual rigid frame bridge high-rise pier pile foundation temperature load the construction camber |
