公路软土路基施工处理与质量控制研究

Study on Construction Treatment and Quality Control of Highway Soft Soil Subgrade

路基作为公路的重要基础,对于公路的路用性能及使用寿命具有重要影响。软土路基作为特殊的路基材料,具有承载力低、含水率高、强度低等特点。在公路的建设过程应采用合理的技术手段对软土路基进行处理,才能保证其达到路基填筑的各项性能要求。对此,应明确公路软土路基的定义,全面分析公路软土路基具备的特点,针对软土路基的特点系统研究现有软土路基的处理方法及应用范围,提出公路软土路基的施工质量控制要点,为公路软土路基的施工和处理提供相关依据。

As an important foundation of highway, subgrade has important influence on road performance and service life of highway. As a special subgrade material, soft soil subgrade has the characteristics of low bearing capacity, high water content and low strength. In the process of highway construction, reason- able technical measures should be adopted to deal with the soft soil subgrade so as to ensure the perfor- mance requirements of the roadbed filling. Therefore, a clear definition of the soft soil roadbed of highway, a comprehensive analysis of the characteristics of highway soft soil roadbed have the characteristics of the system for soft soil subgrade on the scope of the existing methods of soft soil subgrade and its application, put forward the construction quality control of soft soil roadbed of highway, provided the basis for the con- struction and treatment of soft soil highway subgrade.
