Research on seepage deformation and stability of tailings dam in high cold and high altitude areas
In order to study the deformation law of tailings dam under seepage action,the dam body of tailings dam in a cold and high altitude area in Xizang is taken as the research object,and the influence of seepage action on the stability of dam body is studied by analyzing the changes of dam body under the conditions of precipitation and no precipitation.The research results indicate that precipitation has a significant impact on the seepage effect of the dam body,and this enhanced seepage effect directly affects the stability of the dam body.By studying the deformation law of the dam body under seepage,important references can be provided for the design and improve-ment of tailings ponds,further improving their impermeability and seismic performance,and ensuring their long-term safe operation.Therefore,this research achievement is not only of great significance for solving the safety and stability problems of tailings ponds in the cold and high altitude environment in Xizang,but also provides beneficial enlightenment for the safety management of hydraulic structures in similar environments.
