| 摘 要： | 利用透明土模型试验非介入式、可视化的优点，结合PIV(粒子图像测速)技术研究坡顶分级荷载下黏土边坡土体变形规律。试验结果表明:黏土边坡在滑移过程中，土体位移量加速积累，土体变形主要分为稳定、加速和破坏3个阶段；黏土边坡在失稳过程中土体沿坡顶至坡脚半径最大圆弧面滑动，随荷载不断增加，会在边坡内部形成半扇形区域滑裂带。

| Abstract: | The advantages of the non-intrusion and visualization of the transparent soil model test were taken in combination with the PIV (particle image velocimetry) to study the soil deformation law of the clay slope under the graded load of the slope top. Test results show that during the sliding process of the clay slope, the soil displacement accelerates and accumulates. Soil deformation is mainly divided into three stages: stable stage, acceleration stage and failure stage. During the instability process of clay slope, the soil mass slides along the maximum arc surface from the top of the slope to the toe of the slope. With the increasing load, a semi fan-shaped regional slip zone will be formed inside the slope. |
