摘要
针对公路改扩建路基拓宽结合部的常见病害,深入分析其病害的成因———差异沉降。从填筑材料的固结本质、材料选取与施工工艺、拓宽结构设计方面探索了差异沉降机理,并提出了相应的处治方法,为公路改扩建工程提供重要参考。
For the common diseases of embankment widening junction for highway reconstruction and extension,the paper analyzed its causes——differential settlement.From the aspects of consolidation nature of filling materials,materials selection and construction technology etc.,it explored the differential settlement mechanism and proposed a corresponding treatment method for reference.
