Abstract:

Aiming at the seismic safety problems confronting the hydraulic engineering structures in western China,especially the aseismic design of high concrete arch dams,this paper makes a case study of the concrete high arch dam of Xiaowan Hydropower Station,carries out the coupled dynamic analysis of the water-sediment-dam-foundation system of the reservoir,and considers the effects of the complex topography,the reservoir water at the normal storage level,and the sediment due to the year-round operation.The main contents include:¢Ù The free field calculation of complex canyon terrain based on the transfer matrix method and 2D FEM of coupled system of reservoir water-sediment-base; ¢ÚThe 3D seismic analysis algorithm of the reservoir water-sediment-foundation-dam system based on the unified framework of fluid-saturated porous media-solid.Finally,this paper discusses the seismic response laws of the arch dam and the influence of the sediments on the results under the action of the loads of impulse wave and seismic wave,respectively.The results show that the central part of the dam crest will bear larger tensile and compressive stress,while the sediment does not have a significant effect on the displacement and stress of the dam.
