京哈高速公路绥中至沈阳段硬路肩及边坡路基检测与设计建议

Hardened Verge and Slope Subgrade Inspection and Design Suggestions on Section of Suizhong to Shenyang of Jingha Expressway

京哈高速公路绥中至沈阳段长360.4km,因交通量持续增长、服务水平降低,拟对其进行改扩建,对原路路基进行检测评价是项目前期工作的一项重要内容。介绍了硬路肩范围路床和边坡路基检测点位的选定、检测的指标及方法,并对检测数据进行了分析评价,最后提出了对设计阶段的建议。

The section of Suizhong to Shenyang of Jingha Expressway is 360.4km long. Due to the increasing traffic volume and low service level, the reconstruction and expansion is planned to be conducted. The inspection evaluation on the original subgrade is an important content in preparatory work of the project. The index and method of selection and inspection on hardened verge range roadbed and slope subgrade inspection point location are introduced, and analysis evaluation on inspection data is performed and the suggestions on the design stage are proposed at last.
