| Abstract: | Zhejiang Xianju pumped storage power station will be equiped with high-power turbine generator sets. The massive concrete of the volutes would cause high temperature stress and has the risk of thermal cracking. This would affect the normal operation of the whole station. To explore the temperature stress of the spiral case, for unit 1 volute concrete considering the construction process of three-dimensional re-al-time simulation calculation, the stress analysis was carried out on the key position, and recommended measures were put forward to reduce early thermal stress during construction. |
