| 摘 要： | 在真三轴试验的基础上,比较分析了不同含水率对加筋土强度的影响,结果表明:加筋黄土的应力应变曲线均为强硬化型,中主应力比越大,土体抗剪能力越大；在中主应力比一定的情况下,含水率越低,达到相同变形所需要的偏差应力越大,含水率越高,偏差应力越小；黏聚力随中主应力比的变化比内摩擦角随中主应力比的变化更加明显. |
| 关 键 词： | 含水率 加筋土 中主应力比 三轴试验 |

| Abstract: | On the basis of true triaxial test the influence of different moisture content on the strength of reinforced loess is analyzed.The results show that the relation curves of stress-strain of reinforced loess all appear as tough type,and the shear strength becomes bigger with the increase of ratio of intermediate principal stress;for a given ratio of the intermediate principal stress,as the value of moisture content is small,the more bias stress is needed when getting the same deformation,as the value of moist... |
| Keywords: | moisture content reinforced loess ratio of intermediate principal stress triaxial test |
