高等级公路路基拓宽工程处治技术探讨

Discussion on Treatment Technology of High-class Highway Roadbed Widening Project

该文针对高等级公路路基拓宽工程常见的病害,将拓宽路基进行模型简化,通过对实际项目进行计算分析,提出了加强新老路基结合面的处治,路基加筋,拓宽部分路基地基处理,拓宽路基填料及压实度控制等具体处治措施来减小新老路基交界面产生的沉降差。其成果对今后路基拓宽工程实际项目中处治措施的选择、设计和施工具有重要的借鉴和指导意义。

The article simplifies the roadbed widening model for the common faults in the high-class highway roadbed widening projects. According to the calculation analysis of the practical projects, the article puts forward the detail treatment measures to strengthen the treatment of the old and new roadbed connections, the reinforcement of roadbed, the subgrade treatment of widened roadbed, the control of widened roadbed stuffing and compactness to decrease the settlement difference at the interface of the old and new roadbeds. Its result has the important reference and guiding meanings for the selection, design and construction of treatment measures in the future roadbed widening engineering projects.
