　　abstract: the two dimensional finite element methods are used to analyze the large box-like structure of the reverse siphon of the middle route of south-to-north water transfer. there are two kinds of load combinations to affect on the box-like structure. their contributions and status have been considered. it is more efficient to use the fea model in ansys.
