| 摘 要： | 本文运用非饱和土的强度理论分析了膨胀土的强度及其影响因素,对不同含水量的膨胀土进行固结不排水剪切试验。研究了膨胀土强度与其含水量之间的关系,试验表明膨胀土的峰值强度、稳态强度受膨胀土的状态影响强烈。随着含水量的增加,其强度明显下降。随着含水量的变化,粘聚力的变化比其摩擦角变化大。

| Abstract: | In this paper, the strength theory of unsaturated soil is utilized to analyze the strength of expansive soil and its factors influenced. The consolidated undrained shear test is made by using soil sample of different water content. The relationship between the strength of expansive soil and its water content is studied. The results show that the peak value strength and stable state strength of the expansive soil are strongly affected by its water content. With increasing the water content, the strength become apparently lower. The change of coherent force is more than the change of friction angle when the water content of expansive soil is changed. |
