摘　　要：为了提高引调水工程的运行安全,鄂北地区水资源配置工程孟楼~七方倒虹吸采用了3根主管并排布置,主管之间采用连通管相连,形成T型和十字型钢岔管结构。结合该工程的结构型式,采用三维有限元方法对钢岔管结构进行强度设计和安全性复核,确定了各部位结构尺寸。研究结果表明,采用外置的三梁或十字型加强梁分别对T型和十字型钢岔管进行加固,是较优的设计方案。In order to improve the operation safety of the water diversion work of the water resources allocation project in Northen Hubei province,the inverted siphon structure from Menglou to Qifang adopts a side-by-side arrangement with three main pipes.The main pipes are connected by connecting pipes,forming cross-shaped and T-shaped bifurcation structures.Considering the specific structural characteristics of the project,three-dimensioanl finite element method is adopted to analyze the strength of the bifurcation structures and check their safety and determine the structural dimensions of each part.The results show that the optimal design scheme is to use external three-beam or cross-beam reinforcement to strengthen the T-shaped or cross-shaped bifurcation structures respectively.
