Seismic Behavior Analysis for Intake Tower of Luding Hydropower Station
The safety of the structure in the spillway tunnel intake of the hydropower station is very important in the security and benefit of the entire hydropower station. The spillway tunnel intake of luding hydropower station is a large-scale project, especially, with the high NO.2 spillway tunnel intake tower, which has a complex body form and boundary conditions. Through the 3D-FEM static and dynamic analysis of the NO.2 spillway tunnel, the self-vibration characteristics of the intake tower structure is studied. Furthermore, this paper, through the response spectrum method, researched the dynamic response of the intake tower structure, including the dynamic displacement, dynamic stress and the acceleration distribution, by the horizontal earthquake, and demonstrated the safety of the earthquake resistance. The result shows that, the deformation and intensity of the intake tower structure meet demands, however, the stress is very high in the weak region of earthquake-resistant where special measures should be taken to ensure the security of the tower structure. The results of computation will provide a scientific base for the design of the intake tower structure.
