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。
Through the indoor large triaxial test method, the factors affecting the strength of reinforced soil were studied, and the variation of the strength of the specimen under different reinforcement conditions was discussed. The test results show that the effect of reinforcement is more obvious with the increase of axial strain; for the samples with lower strength, the strength after reinforcement is obviously increased; for the same sample, the strength of reinforcement itself is higher, plus The more obvious the effect of ribs is; for the same kind of reinforced material, the more the number of reinforcement layers, the smaller the spacing between the reinforcement layers, the more obvious the reinforcement effect is; the higher the compactness of the specimen itself, the more obvious the reinforcement effect.
