摘　　要：对广西南宁-友谊关高速公路膨胀土路堑边坡施工中出现的大量滑坡问题,进行了详细的现场地质调查,并对其产生原因进行了勘察分析.在此基础上,提出把影响膨胀土边坡破坏的主要因素量化,利用灰色聚类预测理论对膨胀土路堑边坡的稳定性进行预测.结果表明,该预测方法与实际具有较好的吻合性.Aiming at landslide of the expansive soil occurred on Nanning-Youyiguan Highway in Gangxi,a detailed geologic investigation has been carried out to analyse its cause and some leading factors has been digitized to forecast the stability of slope through gray control system model . The results indicate the method is in agreement with the objective reality.
