Abstract

Inverted siphon is a kind of cross-channel building, in order to study the stress distribution law of the buried prestressed inverted siphon structure. The force and deformation characteristics of Xinanpu inverted siphon are analysed by finite element software. In the establishment of finite element calculation model, the arrangement of inverted siphon prestressed reinforcement and the setting of pier are considered. A separate reinforcement calculation model is used to simulate the effect of prestressed reinforcement by applying initial strain, the boundary condition of inverted siphon structure is simulated by the fixed constraint between inverted siphon and pier. By numerical simulation analysis of inverted siphon structure, the cloud maps of stress and displacement and path charts of inverted siphon under various cases are given, then the results are analysed to check the safety performance of inverted siphon, the research results provide a theoretical basis for construction organisation design.
