近几年我国大型公路建设有很多项目施工在山区、丘陵地形上,由于地势的复杂增加了路基施工的难度,很容易发生路基边坡坍方的路基病害,所以有必要加强路基边坡这种路基病害的强调和治理。路基边坡是路基的重要组成部分,对路基稳定起着重要的作用。路基边坡坍方根据其形成的条件及原因,一般可分为:剥落、碎落、滑坡、和崩坍等形式。剥落:边坡土石方表层或风化岩石表面,在湿热、冻融等物理作用下,表面发生胀缩现象,
In recent years, many projects of large-scale highway construction in our country are in mountain and hilly terrain. Due to the complexity of the terrain, it is difficult to embankment construction, so it is easy to cause the roadbed collapse in subgrade slope collapse, so it is necessary to strengthen the roadbed slope Disease stress and governance. Subgrade slope is an important part of the subgrade and plays an important role in roadbed stability. Subgrade slope collapse according to the formation of its conditions and reasons can generally be divided into: spalling, broken down, landslides, collapse collapse and other forms. Peeling off: the slope of earthwork surface or weathered rock surface, in the heat, freeze-thaw and other physical effects, the phenomenon of expansion and contraction surface,
