摘　　要：本文以安徽省滁河驷马山分洪道膨胀土为研究对象,对分洪道不同河段的膨胀土边坡进行取样,开展了膨胀土在不同工况条件下的物理力学试验。通过室内试验和现场监测,获得了膨胀土膨缩变形与土体抗剪强度变化等特征参数。经过对分洪道边坡滑动形成机理和变化规律的调查和分析,提出了膨胀土边坡稳定计算中强度取值的建议和边坡滑动的治理措施,为分洪道扩大工程及其同类工程设计提供了地质依据。The mechanical properties of the expansive soil sampled from different slopes along Simashan flood-diversion channel of Chu River are studied under different working conditions. Based on the results of the indoor experiments and the field monitoring, the corresponding parameters for the swelling and shrinking deformation and the shear strength of the soil are obtained. The mechanism for slope sliding is discussed and the corresponding measures to control the landslide are also suggested, which provide the geological basis for the project and other similar projects.
