高原湿陷性黄土地区冲沟高填方路基施工工艺探究

Study on Construction Technology of Gully High Fill Subgrade in Plateau Collapsible Loess Area

高原湿陷性黄土地区是在特定气候条件下形成的,土质较为特殊,具体表现为以粗颗粒为主体骨架的多孔结构,因此,其在重力作用或者被浸湿的情况下,土层结构会遭到破坏,出现下沉的情况。论文以G213策克至磨憨公路乐都至化隆段为例,对高原湿陷性黄土地区冲沟高填方路基施工工艺进行研究。

The plateau collapsible loess region is formed under specific climatic conditions,and the soil quality is relatively special,which is embodied in the porous structure with coarse particles as the main skeleton.Therefore,under the action of gravity or wetting,the soil layer structure will be damaged and sink.Taking Ledu to Hualong section of G213 Highway from Ceke to Mohan as an example,this paper studies the construction technology ofgullyhigh fill subgrade inplateau collapsible loess area.
