基于GEO-Studio的某尾矿坝动力稳定性分析

Dynamic Stability Analysis of a Tailings Dam Based on GEO-Studio

针对某尾矿坝动力稳定性问题,基于尾矿库实测地形图与岩土地层勘察资料,依据地形概化的方法,建立反映尾矿库地形、地质结构特征的数值计算模型。运用GEO-Studio的QUAKE分析模块进行现状及最终尾矿坝动力稳定性分析,研究了该尾矿坝在地震波作用下的液化情况、加速度响应、位移变化、安全系数的规律,研究结果表明,该尾矿坝可在洪水工况下稳定运行,可以作为工程设计的参考依据。

Aiming at the dynamic stability of a tailings dam,a numerical calculation model reflecting the topography and geological structure characteristics of the tailings reservoir is established based on the measured topographic map and geotechnical survey data of the tailings reservoir and the topographic general⁃ization method.GEO-Studio's QUAKE analysis module was used to analyze the current situation and the fi⁃nal dynamic stability of the tailings dam,and the liquefaction,acceleration response,displacement change and safety factor of the tailings dam under the action of seismic waves were studied.The research results show that the tailings dam can operate stably under flood conditions,and can be used as a reference for engi⁃neering design.
