【摘要】 从微观的角度阐述了膨胀土的胀缩性、裂隙性和超固结性,从而根据膨胀土的三个特性和外部环境因素对膨胀土边坡失稳机理、稳定性进行了分析,揭示了导致膨胀土边坡失稳的机理及影响稳定性的外部环境因素,提出了边坡防护的措施。更多还原

【Abstract】 Expansion,fissures,over-consolidation are referring as properties of expansive soils and were explicated by microcosm in this paper.From these "three properties" and environmental factors on the destructive mechanism was disclosed and the stability analysis was carried out.Eventually,a conclusion was drawn that it is essential to chose proper parameters and computing model in expansive soils slope analysis and additionally corresponding measures to prevent from expansive soils slope destruction.The conclusion available are made use to analyze an engineering instance.更多还原
