EXPERIMENTAL RESEARCH ON SHEAR RHEOLOGICAL CHARACTERISTICS OF BROWN MUDSTONE

摘要：

Through analyzing the achievement of the direct shear rheological tests of brown mudstone, the paper shows linear relationship between normal stress and shear stress in the brown mudstone, and it exists unitize ultimate strain value of rheological character model of coming creep acceleration stage. This paper establishes rheological mechanical model suitable to rheological character of weak layer based on theory of obsolescence. It gets long-term strength equation based on ultimate strain value of coming creep acceleration stage.
