摘要
水电站发电引水系统中，压力钢管的岔管型式多样，结构复杂．三梁式岔管沿相贯线设置椭圆型半环（即加强梁）来承担管段的不平衡力，如何选择加强梁的截面型式，对整个岔管的应力改善具有重要影响．
The form of Y type pipe of penstock is various, its structure is complexed in the diversion system of hydropower station. The three beam Y type pipes take the oval semi cycle(strengthed beam) which is set along the relation curve burden the unbalanced force of pipe reach.How to select the section type of strengthed beam will make influence on the stress improvement of whloe Y type pipe.
