摘　　要：以南水北调工程为背景,使用通用有限元软件ADINA对贴边岔管进行结构计算,分析了补强板的宽度和厚度对岔管结构应力的影响,在此基础上,确定合理的补强板宽度和厚度。通过实例工程的计算,说明使用有限元法进行计算可以了解结构的受力全貌,利于选择合理的工程措施。The study of this paper is based on the South-to-North Water Diversion Project. By using ADINA soft- ware in the structural computation of welted bifurcation, the influence of reinforcement plate width and thickness on the stress of bifurcation structure was analyzed and the reasonable width and thickness of reinforcement plate were deter- mined furtherly in this paper. It would be possible to learn the stress distribution on the whole structure through finite element analysis, which enables us to choose reasonable engineering measures.
