| 摘 要： | 为研究土工织物增强尾矿砂结构的变形、破坏机理 ,室内进行了不同铺设层数下的三轴剪切试验。试验结果表明 :当仅铺设一层土工织物时 ,试件的变形、破坏特征和纯尾矿砂相似 ;随着土工织物铺设层数的增加 ,试件中均出现数个水平连续增强区域 ,抑制剪切变形的进一步发展。试件达到峰值强度后 ,仍有较高的承载能力。最后探讨了连续增强区对加筋土结构强度增长的影响

| Abstract: | Triaxial compression tests are used to study the deformation and failure mechanism of tailings sand reinforced with geotextile under different layer.The results show there are same behavior of deformation and failure between tailings sand reinforced with one layer geotextile and single tailings sand.With the increase in layer number of geotextile, there are many sequentially reinforced sections born in the sample which are parallel to the plane of geotextile and control the development of shear deformation.The samples represent some higher bearing capacity after strength point. The influence come from sequentially reinforced section to the increase of reinforced soil has been discussed lastly. |
