摘　　要：通过挤密碎石桩处理高原斜坡软土地基的实践,指出利用挤密碎石桩结合深渗水盲沟处理斜坡软土地基可以增强坡体的抗滑稳定性,对于坡度较大的斜坡将地基处理和抗滑支挡相结合可确保其路基的稳定性。The effects of subgrade treatment of the plateau slope on soft clay by the compacted stone column are analyzed. It is shown in practice that the stability of the plateau slope soft clay can be increased by combining the compacted stone column and the deep infiltration ditch. So the treatment method of combining the compacted stone column, the deep infiltration ditch and the anti-slide pile can be used if the slope angle of plateau soft clay is large, and in this way the stability of the slope will be ensured.
