    Abstract:

    In this paper, by use of an APPLE-Ⅱ microcomputer controling a dynamic triaxial apparatus made at home, the dynamic strength tests are directly performed on a loess by employing random time histories of seismic load. The method of determining the dynamic strength of loess under the seismic loading from relation curves of dynamic stress and residual strain was presented. And then, the Huihuichuan loess landslide induced by the 1920 Haiyuan earthquake (Ms=8.5) is inverted, and the inverted result coincides with the real seismic damase.
