摘　　要：文章旨在利用ABAQUS有限元分析软件对预应力水闸工程底板结构进行深入研究,确保预应力水闸的安全性和稳定性。以水闸底板和同时浇筑的两侧控制室为研究对象,建立三维非线性有限元模型,对比分析钢筋混凝土结构水闸底板和预应力混凝土结构水闸底板在各种工况下的应力分布情况。结果表明,钢筋混凝土水闸底板在地基反力和扬压力的作用下发生弯曲,上部受拉,下部受压,最大主拉应力发生在上部跨中位置;预应力混凝土结构在预应力作用下最大主拉应力明显减小,满足C40混凝土的抗拉强度,而压应力却有所增加。结论充分阐明了预应力水闸工程底板结构的力学特性,为类似预应力水闸工程设计和施工提供了理论依据和实践指导。The purpose of this paper is to use ABAQUS finite element analysis software to deeply study the base plate structure of prestressed sluice engineering to ensure the safety and stability of prestressed sluice.The base plate of sluice gate and the control rooms on both sides of the sluice gate are studied as the objectives,a three-dimensional nonlinear finite element model is established to compare and analyze the stress distribution of reinforced concrete sluice floor and prestressed concrete sluice floor under various working conditions.The results show that the bottom plate of the reinforced concrete sluice bends under the action of foundation reaction and lifting pressure,the upper part is strained,the lower part is compressed,and the maximum tensile stress occurs in the middle of the upper span.Under the action of prestressing,the maximum principal tensile stress of the prestressed concrete structure decreases obviously,meeting the tensile strength of C40 concrete,while the compressive stress increases.Conclusion describes fully the mechanical characteristics of the base plate structure of prestressed sluice engineering,which provides theoretical basis and practical guidance for the design and construction of similar prestressed sluice engineering.
