| 摘 要： | 利用Geo-slope软件,采用不排水有效应力法,输入美国IMPERIAL山谷地震记录高烈度地震波,对龙都尾矿库堆积坝进行了地震响应的综合分析与液化计算.在烈度为8.5度地震波输入情况下,坝体最大位移为0.004317 m,最大加速度为0.86413 m/s2,放大倍数为2.349倍.计算表明龙都尾矿坝沉积滩将产生裂缝和喷砂,堆积坝出现大面积液化而导致溃坝.

| Abstract: | With the adoption of Geo-slope geotechnical engineering software,the effective stress method without drainage is applied to responses to the earthquake and analysis of liquefaction of Longdu tailings dam by importing high intensity earthquake record wave EL Cento.When 8.5 degree earthquake wave is input,the dam's biggest displacement is 0.004317m and biggest acceleration is 0.86413m/s2,enlarged by 2.349 times.It is indicated by the calculation that the beach of Longdu tailings dam will produce crack and spray sand.Tailings fill dam will produce large-area liquefaction and cause dam break. |
