钢筋混凝土蜗壳由于其有着渐变而不规则的外形,边界条件又很复杂。给结构计算和模型试验的简化处理造成较大的困难,其成果和工程结构实际状态相差较大,因此有必要通过原型试验获得结构在实际运行中的真实应力.本文通过青铜峡电站钢筋混凝土原型结构应力试验,获得了一批钢筋混凝土蜗壳应力的重要资料,在与计算和模型试验进行对比之后,还对蜗壳水箱功能进行了初步探讨,为进一步分析钢筋混凝土蜗壳应力提出了有益的建议.
Reinforced concrete volute due to its gradual and irregular shape, the boundary conditions and very complicated. It is difficult to simplify the structure calculation and model test, and the result differs greatly from the actual state of the engineering structure.Therefore, it is necessary to obtain the real stress of the structure in actual operation through the prototype test.Through the prototype of the reinforced concrete of Qingtongxia Hydropower Station Structural stress test, obtained a number of important information on the volute stress of reinforced concrete. Comparing with the calculation and model tests, the function of volute tank was also discussed. It is helpful to further analyze the stress of the volute of reinforced concrete Suggest.
