| Abstract: | In combination with practice of Xiaowan power station, a three-dimension model of the whole hydropower house iincluding the pier composite structure is created, the static and dynamic stiffness of the pier composite structure is studied. The displacement and stress of the pier under dynamic loads of the water turbine generating sets is calculated by dynamic method.The results indicate that the dynamic stiffness partly depends on the load frequency and the dynamle analysis is more reliable.Dynamic method calculation indicates that stiffness and intenslty of the pler composlte structure basically meet the design requirements. |
