【摘要】 通过离心模型试验对土工格室加筋边坡变形和破坏机理进行了研究,试验表明,土工格室加筋边坡破坏过程可划分为变形、开裂、局部剪切塑性变形和破坏4个阶段.土工格室加筋边坡的破坏模式表现为加筋区的整体破坏,并与未加筋区有明显的分界线.结合数值分析方法,分析了土工格室加筋边坡破坏模式和影响因素,在此基础上提出了加筋路堤边坡设计方法,并应用于某二级公路加筋路堤.更多还原

【Abstract】 Regard some ClassⅡhighway as the prototype embankment,the geogrids-reinforced slope defor- mation and destroying mechanics mechanism have carried on the centrifuge model tests..Test find that geo- grids-reinforced slope destroy course can divide out of shape,fracture,some shear plastic strain and failure 4 stages,the destruction mode of the geogrids-reinforced slope is shown as the whole destruction with the muscle district,and there is obvious boundary line with that not added muscle district.And combined with numerical analysis methods,the geogrids-reinforced slope failure mode and influencing factors are studied.Basing on these, the design method of geogrids-reinforced slope is put forward.更多还原
