| 摘 要： | 通过室内大三轴试验方法，对加筋土强度影响因素进行了研究，探讨了在不同加筋情况下试样强度的变化规律。试验结果表明：加筋作用的效果随着轴向应变增大而作用越明显；对于强度较低的试样，加筋后强度提高明显；对于同一试样，加筋材料本身强度越高，加筋效果越明显；对于同一种加筋材料，加筋层数越多，筋层间距越小，加筋效果越明显；试样自身的密实度越高，加筋效果越明显。

| Abstract: | Researches on factors affecting strength of reinforced soil are performed by using lab triaxial tests.The change law of strength of samples with different reinforced conditions is discussed,and the corresponding factors are tested.The results show that the effect of the reinforced action becomes obviously while the axial strain increases;for the samples with low strength,the strength increases greatly after being reinforced;for the same samples,the higher the strength of reinforced material is,the more obvi... |
