摘　　要：采用通用的有限元计算软件分析了水电站对称Y形钢筋混凝土岔管结构,计算出了钢筋混凝土岔管结构环向应力及变形的分布情况,并分析了内水压力对岔管围岩的影响。计算结果表明,采用钢筋混凝土岔管结构是安全可靠的,能够满足工程要求。Adopting the general finite element computation software to analyze symmetry Y-type reinforced concrete bifurcation pipe in Hydropower Station, this paper has calculated annular stress and distortion distribution of reinforced concrete bifurcation pipe, and analyzed the influence that indide hydraulic pressure has on bifurcation pipe wall rock. The computed result indicates that, using reinforced concrete bifurcation pipe is safe and reliable, and can satisfy the project, se computed result indicated.
