摘　　要：滑坡稳定性评价是重大工程地质问题之一。通过对某拟建高速公路古滑坡进行详细的地质勘察并取样试验,系统地揭示了古滑坡的特征、成因;确定了滑坡计算的参数和边界条件;采用传递系数法分别对该古滑坡在工程开挖前与开挖后进行稳定性计算,认为工程开挖后,该古滑坡在降雨工况下极有可能复活,在地震工况下处于失稳下滑状态。Landslide stability evaluation is one of the significant problems of engineering geology. On basis of the detailed geological survey and sampling test on an ancient landslide along a planned highway, the characteristics and genesis of the ancient landslide was disclosed systematically herein with the parameters and boundary conditions of landslide calculation specified; then transfer coefficient method was used to calculate the landslide stability before and after excavation respectively. It is concluded that, after excavation, the ancient landslide is extremely likely to reactive in case of rainfall, and tends to be failure in case of earthquake.
