    STUDY ON THE TEST OF TENSILE STRENGTH OF LOESS IN THE SOUTH OF JINGHE

    • Through the uniaxial tensile test of loess samples,the tensile fracture characteristics of undisturbed loess in the south bank of Jinghe river. The study shows that the moisture content is the important factor for the tensile strength of loess, and they have decreasing power function relationship with the tensile strength of loess. Under uniaxial tensile test of the loess, the ultimate tensile strain of loess is several over ten thousand, and the tensile strength is several or tens of KPa. Under the condition of rain and irrigation, the tensile strength of loess future decreases and the fissure of the rear edge of the loess slope further development, it is the one of factors that results in the loess landslide.
