对两种不同的渠道深度和渠底地基厚度的自重湿陷性黄土渠道进行浸水变形的离心模型试验 ,得到了渠道浸水变形、渠道边坡破坏形式及边坡内部土体吸力的变化过程。该项研究对非饱和黄土的结构性、湿陷变形、吸力量测及变化等问题 ,具有理论和实际意义 Centrifugal model test of submerged collapsible loess channel with two different channel depths and bottom thicknesses is carried out. The change process of channel immersion deformation, channel slope failure mode and soil suction in slope are obtained. The study has theoretical and practical significance for the structural, collapsible deformation, suction measurement and variation of unsaturated loess
