摘要
通过离心模型试验,研究了干湿循环下膨胀土边坡的变形和稳定性.分析了裂缝的发生和发展过程,以及水份入渗对膨胀土边坡稳定性的影响.揭示了膨胀土边坡失稳的破坏机理.
A series of geotechnical centrifuge model tests were carried out to study the influences of alternation between drying and wetting on the deformation and stability of the expansive soil slope. The influences of cracks and infiltration on the stability of expansive soil slope were analyzed and the mechanism of the failure of expansive soil slope was investigated.
