摘要
本文在研究大石河尾矿砂的稳态特性及分析前人研究成果的基础上初步提出了一个改进的用德态理论分析尾矿坝地震液化和稳定的方法，并按照此方法对大石河尾矿坝在１９７６年唐山地震时的液化和稳定特性进行了分析，分析结果与宏观震害现象基本符合。文中对稳态理论在实际应用中存在的问题进行了讨论．
Based on the research of steady-state strength of Dashihe tailings and review about the developmint and application of steady-state strength theory,an improved steady-state strength analysis procedure is proposed on liquefaction and stability of tailings dam Following this procedure,the liquefaction and stability of the 1976 Dashihe tailings dam is investigated during the 1976 Tangshan Earthquake.The results are basically consentient with the seismic damage.It is discussed to apply the stedy-state strength to soil structure.
