摘要
本文通过对公路拓宽工程国内外相关资料以及上海、重庆等地实体工程的调查研究,对其典型病害和损坏机理进行了系统研究。在新老路基差异变形形成和其对路面结构响应方面作了深入分析的基础上,提出了以路基稳定为前提,新老路基不协调变形控制为核心的路基拓宽设计理论,并在实体工程中得到较好的验证。
According to domestic and foreign highway widening reference materials and study on some real engineering in Shanghai and Chongqing, typical distress and damaged reason is studied. It analyses the formation mechanism of differential deformation between new and old roadbed and its respond to pavement structure. A design theory to control the imbalanced deformation between new and old roads through embankment stabilization, which has verified by real engineering, is brought forward.
