| 摘 要： | 采用室内大三轴试验对不同密度与不同加筋层数的加筋碎石进行试验研究,得到了不同加筋复合体的应力应变特性,并对试验结果与加筋机理进行分析,试验结果表明:加筋土的加筋效果与加筋层、填料密度以及加筋材料等有关,加筋土的加筋机理符合“准粘聚力”理论。研究结果可用于指导设计与施工。

| Abstract: | Reinforced crushed-stone soil mixture with different density and with different number of layers of reinforcement was tested with laboratory macro-triaxial testing procedures to obtain the stress and strain characteris- tics of different types of reinforced crushed-stone soil mixtures. The results of the tests and the mechanism of the reinforcement were analyzed. The test results showed that the reinforcing effect of reinforced soil mixture is related with the layers of reinforcement, density of fill material and reinforcing material. The reinforcing mechanism of the reinforced soil mixture was in compliance with the "quasi cohesive force" theory. The research results may be of guidance for designs and construction projects. |
