高速公路山皮土路基填筑关键技术研究

Study on Key Technology of Hillside Soil Filling of Expressway Roadbed

以塘承高速公路二期工程为例,结合工程所在地区天津市蓟县的料源情况,为充分利用当地资源,减少对土地的破坏,高速公路路基填筑采用山皮土,通过对山皮土路基填筑的关键问题:料源、施工工艺及机械组合、松铺厚度、检测方法等方面的研究,可供山岭较多但土源缺乏地区的高等级道路山皮土路基填筑的设计与施工参考。

Taking Tangcheng Expressway Phase II Project as an example, the article introduces the hillside soil used for the roadbed filling of expressway according to the material source status of Tianjin Ji County where the project is located in order fully to utilize the local resources and to decrease the land damage. The article studies the material source, construction technology, mechanical combination, laying thickness and inspection method in the key issues of hillside soil roadbed filling, which can be referred for the design and construction of the hillside soil roadbed filling of the high-class roads in the regions with more mountains, but the lack of soil source.
