摘　　要：针对大型涵洞式渡槽结构体型大、受力复杂等特点,以沙河渡槽为例,采用大型有限元软件对涵洞式渡槽结构进行仿真分析,给出渡槽结构在运营期过程中各工况下应力及变形分布规律,并分析各种单荷载因素对渡槽变形的影响,研究渡槽结构设计方案的合理性。分析表明,所选用的沙河涵洞式渡槽结构合理,设计满足要求。研究成果可为涵洞式渡槽的设计提供一定参考价值。According to the characteristics of large-scale culvert aqueduct structure,such as large size and complex stress,taking Shahe aqueduct as an example,the culvert aqueduct structure is simulated and analyzed by using large-scale finite element software.The distribution law of stress and deformation of aqueduct structure under various working conditions during operation period is given,the influence of various single load factors on aqueduct deformation is analyzed,and the rationality of aqueduct structure design scheme is studied.The analysis shows that the structure of Shahe culvert aqueduct is reasonable and the design meets the requirements.The research results provide a certain reference value for the design of culvert aqueduct.
