落脚河水电站钢筋混凝土岔管有限元分析

Finite element analysis for reinforced concrete bifurcation pipein Luojiaohe Hydropower Station

对落脚河水电站钢筋混凝土岔管进行了三维有限元分析.计算了在施工和运行过程中的6种组合工况下钢筋混凝土岔管的应力和变形.同时,经分析认为在岔管相贯部位采取了加腋措施,可有效缓解岔管部位的应力集中.

Three-dimensional finite element analysis for the reinforced concrete bifurcation pipe in Luojiaohe Hydropower Station is carried out. The stress and deformation of the reinforced concrete bifurcation with six combined operating conditions in the phases of construction and operating are calculated. Meanwhile, the intersection part of the bifurcation pipe is haunched, which helps to relief the stress concentration of the bifurcation pipe.
