摘要
结合南水北调中线工程河南段某大型倒虹吸结构,运用有限元软件ANSYS,采用整体式配筋模型,对结构管身几种不同特殊工况进行非线性有限元受力情况进行分析.分析结果表明:当压实回填后结构内无水和停水检修时对结构最不利,最不利位置发生在结构跨中内侧,在设计和施工中应采取有效措施.
Abstract
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.
