摘　　要：近年来国内外学者对膨胀土的特性进行了广泛深入的研究,笔者着重从膨胀土的胀缩性、裂隙性、超固结性、渗透性等几个方面总结了膨胀土的研究现状及进展。并对膨胀土边坡常采用的防护措施,如换填法、化学改良法、支挡结构和生态防护进行了归纳总结。最后从膨胀土成份分析、生态防护方法、适宜植物物种选择以及原位试验等领域对膨胀土边坡生态防护研究提出了新思路。本文研究成果对膨胀土边坡防治的后续研究和工程应用提供借鉴。In recent years,domestic and foreign scholars have made extensive and in-depth research on the characteristics of expansive soil.The author summarizes the research status and progress of expansive soil from the aspects of expansion and contraction,fissure,overconsolidation,permeability and so on.The common protective measures of expansive soil slope,such as replacement,chemical improvement,retaining structure and ecological protection,are summarized.Finally,a new idea for the study of expansive Soil Slope Ecological Protection is put forward in the fields of expansive soil composition analysis,ecological protection method,suitable plant species selection and in-situ test.The research results of this paper can be used for reference for the follow-up study and engineering application of expansive Soil Slope Control.
