摘　　要：土工织物加筋是工程中加固土体的有效方式。进行了坡脚开挖条件下素土坡与土工织物加筋土坡的离心模型试验,测量了边坡的位移变化,分析了土体的变形破坏过程与土工织物的作用。试验结果表明土工织物加筋减小了滑动体的位移,提高了土坡的稳定性,改变了滑裂面的形态。土工织物加筋使边坡变形均匀化,牵拉外侧土体,从而延迟并减轻了边坡破坏。The geotextile reinforcement is an effective way to strengthen soils in engineering.The centrifuge modeling of plain soil slope and geotextile-reinforced slope under excavation of slope foot is carried out,the displacement change of slopes is measured,and the deformation and failure process of soils and the action of geotextile are analyzed.The test results show that the geotextile reinforcement reduces the displacement of the sliding body,improves the stability of the soil slopes and changes the shape of the slip surface.The geotextile reinforcement homogenizes the slope deformation and pulls the outer soil,thus delaying and reducing the slope failure.
