An aqueduct is a water conveyance structure that enables channel flow across canals, valleys, depressions, roads, and other structures. The optimal structural selection of the aqueduct is particularly important to ensure engineering quality and optimize project investment. To optimize the design of an aqueduct structure, this study established a mathematical model based on the three-dimensional finite element method that considers the temperature field and structural stress field coupling among its design parameters. The model was used to optimize and design the main wall thickness and tie spacings of the aqueduct structure. The Caohe aqueduct was considered as an example for the proposed design. The influences of temperature-induced stress on the reinforced concrete structure of the aqueduct in winter and summer were investigated based on the actual engineering conditions of the structure, and the corresponding structural optimization was obtained. The results showed that the optimized aqueduct can offset temperature and structural stresses, thus reducing the amount of material required. The maximum generated stress was also lower than that of the original design. Furthermore, this study is expected to provide guidance for similar engineering construction projects.

考虑温度影响的混凝土渡槽结构设计优化
渡槽是一种水输送结构,能够使通道流经运河,山谷,洼地,道路和其他结构。渡槽的最佳结构选择对于确保工程质量和优化项目投资尤为重要。为了优化渡槽结构的设计,本研究基于三维有限元方法建立了一个数学模型,该模型考虑了温度场和结构应力场在其设计参数之间的耦合。该模型用于优化和设计渡槽结构的主壁厚度和连接间距。he河渡槽被认为是该设计的一个例子。根据结构的实际工程条件,研究了冬季和夏季温度引起的应力对渡槽钢筋混凝土结构的影响,并进行了相应的结构优化。结果表明,优化的渡槽可以抵消温度和结构应力,从而减少了所需的材料量。最大产生应力也低于原始设计。此外,该研究有望为类似的工程建设项目提供指导。最大产生应力也低于原始设计。此外,该研究有望为类似的工程建设项目提供指导。最大产生应力也低于原始设计。此外,该研究有望为类似的工程建设项目提供指导。
