Abstract: In order to study the stress and deformation distribution of the inverted siphon bridge project. The finite element method is used to analyse the force of the bridge inverted siphon in operating period, the finite element model of bridge inverted siphon structure is established according to the actual engineering conditions. The results show that, the stress change in the inverted siphon is mainly caused by internal water pressure, water pressure is an important load of inverted siphon structure design, the stress value of inverted siphon pipe inner surface is greater than that of outer surface, there was obvious stress concentration at the support of the inverted siphon, local reinforcement should be used in design.

Keywords: inverted siphon; operating period; finite element method; simulation model; stress distribution.
