Nonlinear Finite Element Analysis of Inverted Siphon
Based on a large inverted siphon structure in Henan section ofSouth to North Water Diversion Project,this paper uses the finite element software ANSYS and adopts an integral reinforcement model to analyze the nonlinear finite element stress situation of several different special working conditions of the structural pipe body.The analysis results indicate that the most unfavorable position for the structure is when there is no water or water is stopped for maintenance after compaction and backfilling.The most unfavorable position occurs on the inner side of the mid span of the structure,and effective measures should be taken in design and construction.
