Dynamic Reaction Analysis of Tailing Dams Under Earthquake

Xiong, Bao-Lin / Wang, Xi-Liang / Lu, Chun-Jiao

Abstract The nonlinear idiosyncrasy of soil in tailings dam with viscous damping can be simplified as oscillation system of equivalent viscoelasticity. By this means, dynamic reaction of tailings dam during earthquake is analyzed. Then peak acceleration of ground motion in base rock, predominant period and equivalent times of cyclic action are investigated. Acceleration reaction and isoline of principal stress of representative cross section during earthquake are discussed. The preliminary results show that dynamic reaction of dam during earthquake rests on earthquake inputting of base rock and mechanical specialty of tailings dam materials.
