| 摘 要： | 云南某尾矿库设计将排土场修整后作为尾矿坝,形成的宽顶废石坝最大坝高182m,坝顶宽度496m,尾矿坝处于8度地震烈度区。采用等效线性黏—弹性模型,对宽顶废石尾矿坝的动力响应进行分析,得出高地震烈度条件下坝体加速度、动应力及动力稳定性。研究结果对高地震烈度区尾矿坝工程建设具有指导意义。

| Abstract: | A waste dump in Yunnan was designed to be a tailings dam which formed a wide top waste rock dam with maximum height of 182 m and 496 m crest width. The tailings dam is located in 8 degree seismic intensity zone. The dynamic response of wide top waste rock tailings dam under high seismic intensity is analyzed by using the equivalent linear viscosity-elasticity model. The acceleration, dynamic stress and dynamic stability of dam body are calculated. The results of the study have a guiding significance for the construction of tailings dam in high seismic intensity area. |
