泥岩填石路堤施工技术应用

Application of construction technology of mudstone rock-fill embankment

泥岩本身为泥质结构,在饱水状态下3～4 h即刻崩解。用于路基填料,泥岩变形大,造成路基不稳定,易诱发路基沉陷、变形等病害。文章结合工程实例,分析了泥岩填石路堤施工技术方案的可行性及可操作性。

Mudstone is shale structure,it may crumble if it stays in saturated state for 3～4 hours.If used as roadbed filling,mudstone may be out of shape,which leads to the roadbed to be unstable,induces damages such as roadbed subsidence and deformation.Combining with engineering example,this paper analyzes the feasibility and maneuverability of construction technology methods of mudstone rock-fill embankment.
