| Abstract: | By considering structural material,geometric dimensions and other nonlinear factors,ABAQUS finite element software is applied to build up a three-dimensional numerical model for the navigation lock head.Through the reasonable interaction among side piers,bottom floor,backfill soil and foundation of the navigation lock head,the structure internal forces of navigation lock head are calculated respectively under different working conditions.After the rationality of calculation result is verified,it is discussed the advantages and disadvantages to adopt the analytic way and finite element method for structure internal force analysis as well as the applicable conditions. |
