介绍沼河渡槽如何建模,边界约束的处理,预应力的等效施加,采用三维有限元的方法对南水北调洺河渡槽进行了分析,计算出在不同的工况下整体的应力,为工程设计提供了科学依据。
This paper introduces how to model the marsh aqueduct, treat the boundary constraint and the equivalent prestressing. The three-dimensional finite element method is used to analyze the Fehe aqueduct of the South-to-North Water Diversion Project to calculate the overall stress under different working conditions. Provide a scientific basis.
