混凝土损伤塑性模型在软基上船闸设计中的应用

利用有限元计算软件ABAQUS, 以某软基上的船闸闸首为基本计算结构, 建立了闸首- 地基三维有限元模 型, 分析了在同一工况下弹性模型和弹塑性模型的应力分布规律, 求出了配筋模型中钢筋的拉应力, 并根据计算结 果及相关公式对配筋效果进行了检验。检验结果显示, 配筋设计符合安全要求。 Acco rding to the basic calculation st ructur e of a ship lock head on the soft foundatio n, a thr ee2dimensional finite ele2 ment model of lock head and foundation was developed using finite element software ABAQUS. The stress distributions of elastic model and elastoplastic model under the same w orking condit ions w ere calculated and analyzed. The tensile stress of the reinforced model was calculated. Finally , the reinfo rcement effects w er e ver ified based on the calculation results and relev ant fo rmula. 2014 年江苏省普通高校研究生科研实践计划项目/ 软基上船闸结构优化设计和质量通病防控技术研究0 ( 2014B25514)
