摘　　要：以横山咀渡槽工程为例,采用有限单元法对其抛物线拱圈进行计算分析,得出不同荷载组合作用下结构内力及变形位移。结果表明,横山咀渡槽拱圈结构内力分布符合规律,应力水平较低;各截面配筋符合规范要求,且安全裕度较大。研究成果可为同类型渡槽拱圈结构受力分析求解提供参考。Taking the Hengshanzui Aqueduct project as an example,the finite element method is used to calculate and analyze the parabolic arch ring,and the internal forces and deformation displacements of the structure under different load combinations are obtained.The results show that the internal force distribution of the arch ring structure of Hengshanzui Aqueduct conforms to the law,and the stress level is relatively low;The reinforcement of each section meets the requirements of the specifications and has a large safety margin.This method can provide reference for the stress analysis and solution of arch ring structures in the same type of aqueduct.
