摘要: 笔者在本文通过在南友路膨胀土依托工程的施工与研究,根据膨胀土的工程特性简要的分析了膨胀土路堑 边坡破坏的机理,介绍采用树根桩+CMA混合溶液为主,并辅以其它必要措施相结合的膨胀土路堑边坡加固防护 方案.论述了该方案在膨胀土地区的应用机理及范围,并对方案的设计、施工工艺以及施工质量的控制进行了讨 论.

关键词: 膨胀土, 树根桩, 路堑边坡, CMA混合溶液, 设计与施工

Abstract: Get across expansive-soil construction and research in nanyuu highway,simple analyzing destructive reason in expansive-soil cutting slope on the basis of engineering characteristic of expansive-soil.Introduce reinforce protection scheme of root-pile+ CMA blend, which assist with otber required measure. Application mechanism and range of this scheme in the expansive areas is discussed, and scheme design.construction technology and quality control are set forth emphatically in this paper.

Key words: expansive-soil, root-pile, cutting-slope, DAH blend, design and construction
