| abstracts | The paper deals with the stability analysis of tailings dam subjected to dynamic loading induced
by mining shocks which occurred in neighbouring copper mine. The main goal of the paper was to model
the dynamic response of the dam during two extreme paraseismic events which occurred in 2016 based on
accelerograms recorded at the dam toe. Dynamic response of the tailings dam was calculated using finite
element method and the implicit time-integration method implemented in commercial codes. The boundary
condition corresponding to dynamic loading was determined by deconvolution procedure. The error
analysis showed that most precise signal reproduction is achieved while using target signal with peak value
reduced by 40% as a test signal. Both acceleration and displacement time-series were successfully
reproduced. Moreover, the stability analysis was conducted for five independent signals with design peak
horizontal acceleration and showed that no permanent displacements should occur. The temporary
horizontal displacement of the dam crest should not exceed 13 mm, assuming equivalent linear material
model. |
