| 摘 要： | 本文使用目前国际上广泛流行的坝体地震反应分析方法，对遭受１９７６年唐山地震袭击的大石河尾矿坝进行了分析。并将分析结果与Ｓｅｅｄ简化法、一维反应分析方法的结果进行了对比。分析结果表明，二维总应力分析方法定性上能较为合理地给出坝体地震反应情况，Ｓｅｅｄ简化法直接用于坝体液化分析存在着一些问题，需要进一步改进。

| Abstract: | The Dashihe tailings dam which Suffered the Tangshan Earthquake in 1976 was analyzed by using program QUAD-4 which is used to analyze seismic response of dam worldwide. The results were compared with those of Seed's simplified method and 1-D analyse and the computed results were compact with the seismic performance of the 1976 dam. Comparison shows that program QUAD-4 provides a better analysis qualitatively and the Seed's method needs to improve for analyzing seismic responses of dam. |
