公路切割古滑体的宏观破坏特征与治理对策

The Macro-Failure Characteristic of the Highway on the Old Landslide and the Solving Methods

从古滑体内路堑切割所导致的路堑边坡稳定、路面至古滑床残留土柱稳定。 古滑体稳定及土体渗流应力作用出发，论述了其宏观破坏特征、原因、机制、过程，确 定了稳坡对策、方案与措施．

By studying the roadside slope stability of the highway whose base had cut the old landslide, the stability between the road surface and the remaining soil post of the old landslide, the stability of the old landslide, and the stress of the edaphic humidity, the macao-failure characteristic, cause, principle, process of the old landslide were analyzed, the solving methods, proposals and steps to enhance the roadside slope stability were defined. This methods may be used successfully in the similar collapse of the roadside slope on the old landslide.
