| 摘 要： | 考虑了纤维材料的尺寸效应,采用常规三轴仪研究了纤维土在不固结、不排水条件下的强度特性和补强机理。试验结果表明,该纤维土的强度和整体稳定性较素土有明显提高,是由于纤维弯曲与土颗粒均匀地交织在一起构成了空间(三维)结构,土体与纤维之间产生咬合摩擦力和空间约束力所致。同时试验还表明,纤维掺量和围压也是决定纤维土性质的重要因素。

| Abstract: | Considering the dimension effect of the fiber,the general triaxial experiment instrument is used to study the intensity characteristics and reinforced mechanism of the fibrous soil under the unconsolidated-undrained condition in Inner Mongolia.The results indicate that the soil's strength and stability are improved obviously comparing with the soil without fiber.It is because the fiber and soil are mixed equably to constitute a spatial(three-dimensional) structure,and there are the occluded friction force a... |
