摘要
通过室内加筋三轴剪切试验,得出最优含水率附近两种不同含水率的加筋膨胀土的应力-应变关系曲线。分析试验曲线可知,相同含水率时试样的强度随着加筋层数、周围压力的增加而增大;同围压、同加筋层数的试样的含水率略微的减少,引起强度明显的增加,表明加筋膨胀土强度的水敏感性。
The stress-swain curves of two kinds of reinforced expansive soil with different water contents around optimal value are obtained by triaxial shear test on reinforced soils. The strength of the sample with the same water contents gets stronger with the increase of reinforced layers and confinement pressure; the strength of the sample under the same confinement pressure and reinforced layers increases obviously by reducing slightly its water contents; and the result that the strength of reinforced expansive soil is sensitive to water contents is gained by analyzing the test curves.
