土质路堑边坡失稳破坏往往表现为土体位移。以重庆铜合高速公路K22+770~K22+965段路堑边坡位移预测为例，对基于灰色理论构建的土质路堑边坡位移预测灰色模型进行介绍，并将预测值与实测数据进行比较，结果表明其准确度高。在此基础上建立位移随监测时间变化的响应函数，其适用性强，可作为土质路堑边坡位移预测的经验公式。
土質路塹邊坡失穩破壞往往錶現為土體位移。以重慶銅閤高速公路K22+770~K22+965段路塹邊坡位移預測為例，對基于灰色理論構建的土質路塹邊坡位移預測灰色模型進行介紹，併將預測值與實測數據進行比較，結果錶明其準確度高。在此基礎上建立位移隨鑑測時間變化的響應函數，其適用性彊，可作為土質路塹邊坡位移預測的經驗公式。

Buckling failure of soil cutting slope usually reflects in displacement of soil mass. With the forecast for displacement of cutting slope on section K22+770 ~ K22+965 of Chongqing Tongliang-Hechuan Expressway as an example, this paper introduces forecasting grey model of displacement of soil cutting slope established based on grey theoretical structure and compares the forecast values with the measured data, the result shows high accuracy. On this basis the paper establishes response function of displacement changing with monitoring time, this function has strong adaptability and can be used as empirical formula of forecast for displacement of soil cutting slope.
