摘要
基于拓扑优化设计理论和方法,研究空箱挡土墙结构优化设计问题。以清隆桥泵站进水侧空箱挡土墙为例,以挡墙应变能最小为目标函数,以挡墙结构体积、强度、抗滑稳定、抗倾覆稳定等为约束条件构建拓扑优化计算模型,实现了对空箱挡土墙的结构优化及轻量化设计。利用有限元软件对优化后的结构进行稳定性复核,结果表明空箱挡土墙结构的强度、抗滑稳定、基地应力等指标均满足要求,验证了拓扑优化结果的可靠性,为挡土墙结构优化设计提供参考。
Based on topological optimization design theory and method, the optimization design of chamber retaining wall structure is studied. Taking Qinglongqiao Pump station inlet side chamber retaining wall as an example, taking the minimum strain energy of the retaining wall as the objective function, and taking the volume,strength, anti-sliding stability, anti-overturning stability of the retaining wall as the constraint conditions, the topological optimization calculation model is established to realize the structural optimization and lightweight design of the chamber retaining wall. Finite element software is used to recheck the stability of the optimized structure, and the results show that the strength, anti-sliding stability, base stress and other indicators of the chamber retaining wall structure met the requirements, which verified the reliability of the topological optimization results, and provide a reference for the optimization design of the retaining wall structure.
