摘　　要：通过对CMA生态改性剂的改性原理的简单介绍,研究了蒙华铁路膨胀土路堑施工中的应用效果。CMA膨胀土生态改性剂的应用是采用一种化学方式处理膨胀土的施工技术,该技术方法实用且简单,提高了改性施工后的的路堑边坡土体强度和稳定性,起到了边坡绿化美化的功能。本文探讨了CMA生态改性剂应用技术对膨胀土路堑边坡改性以及边坡绿化恢复,通过改性后的膨胀土具有较好的工程效果。Through the brief introduction of the modification principle of CMA ecological modifier, its application effect in the expansive soil roadway construction of Menghua Railway is studied. The application of CMA expansive soil ecological modifier is to use a chemical construction method for treating expansive soil. The technical method is practical and simple, and improves the strength and stability of the roadway slope after modified construction and it has the function of landscaping and beautification. In this paper, the application technology of CMA ecological modifier is applied to the modification of expansive soil cutting slope and the restoration of slope greening. The modified expansive soil has good engineering effect.
