摘　　要：钢岔管设计是水电站引水系统设计中的重要一环,水平底钢岔管相较传统的钢岔管具有检修排水方便的优势,这一新型结构形式有望在水利水电工程中得到推广应用。以某水电站工程为例,借助ANSYS有限元分析软件对水平底钢岔管体型进行数值模拟计算,获取岔管整体和局部应力水平和分布情况,由此检验水平底钢岔管结构合理性及是否满足设计要求,并与同部位传统上下对称月牙肋岔管进行应力对比分析。The design of steel bifurcations is a critical component of water conveyance system in hydropower projects.Compared to traditional steel bifurcations,flat-bottomed bifurcations offer advantages such as easier maintenance and drainage,making this innovative structural form a promising candidate for widespread application in water conservancy and hydropower projects.This study focuses on a specific hydropower project and employs ANSYS finite element software to perform numerical simulations of the flat-bottomed bifurcation geometry.The simulations provide insights into both the overall and local stress levels and distributions within the bifurcation,enabling the evaluation of the structural rationality and compliance with design requirements.Additionally,a comparative stress analysis is conducted between the flat-bottomed bifurcations and traditional symmetrical crescent-ribbed bifurcations at corresponding locations.
