通过三轴压缩试验，研究了不同深度边坡取样、不同围压和含水率的天然黄土的变形破坏特征，并根据黄土试样的微观结构分析了其原因。根据上述结果，解释了荷载条件下黄土边坡变形破坏的过程。试验结果表明，不同深度边坡取样、不同围压和含水率的天然黄土具有良好的变形破坏特性。应力应变曲线和抗剪强度的不同特点。黄土边坡特殊的工程地质条件导致含水量与围压的结合不利于黄土强度的维持，从而导致黄土及黄土边坡的破坏。
By means of triaxial compression test,the characteristics of deformation and failure of the natural loess which is sampled from the different depth of slope and has different confining pressure and moisture content are researched,and the reasons are analyzed according to the microstructure of loess samples.According to the above results,the process of deformation and failure of the loess slope under load condition are explained.The test results show that the natural loess which is sampled from the different depth of slope and has different confining pressure and moisture content have the different characteristics of stress-stain curves and the shear strength.The special conditions of engineering geology of loess slope result in the combination of moisture content and confining pressure that is adverse to maintain the strength of loess,this can result in the failure of loess and loess slope.
