水塘湿地地区公路包边土板岩路基施工方法研究

Research on Construction Method of Highway Slab Slate Rock Subgrade in Reservoir Wetland Area

在星沙联络线道路K0+000~K0+945合同试验段板岩填筑路基中采用了换填、分层碾压、粘土包边技术,该项技术中:换填,具有增强地基强度有效控制地基沉降的作用;控制压实度,能有效地控制路基沉降;粘土包边,具有保护边坡、防止水体渗入路基导致板岩多次崩解而沉降过大的作用,该方法外形美观、施工工艺简单、质量可靠等优点,其社会效益尤为显著。

This paper adopts the technology of replacement,layer rolling and clay edging in the slate filling roadbed of the contract test section of Xingsha Link Road K0+000~K0+945.In this technology:replacement,with reinforcement The foundation strength effectively controls the settlement of the foundation;controlling the compaction degree can effectively control the settlement of the roadbed;the clay edging has the protection slope and prevents the water body from infiltrating into the roadbed,causing the shale to disintegrate and collapse too much.The method is beautiful.The construction process is simple,the quality is reliable,and so on,its social benefits are particularly significant.
