| 摘 要： | 利用有限元计算软件ABAQUS,考虑混凝土的塑性变化,以某软基上的船闸闸室为基本计算结构,分析了不同工况下弹性模型和弹塑性模型的应力应变分布规律。通过对比可以发现,弹塑性模型得出的结果更符合实际受力情况,可为设计人员配筋设计提供参考。

| Abstract: | Considering concrete plastic change,we build a three-dimensional finite element model of lock chamber-foundation with ABAQUS.Regarding a lock chamber on the soft base as a basic computing structure,we analyze the stress distribution and deformation characteristics under different working conditions of elastic model and elastoplastic model.The results show that the elastoplastic model is conservative,which can provide reference for the reinforcement design. |
