摘　　要：考虑结构材料和几何尺度等非线性因素,应用ABAQUS有限元软件建立船闸闸首部位的三维数值模型;通过合理设置闸首部位边墩、底板、回填土和地基之间的接触,分别计算不同工况条件下闸首的结构内力;在验证计算成果合理性的基础上,探讨采用解析法和有限元法进行结构内力分析的优缺点及其适用条件。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.
