摘要
针对市区旧路拓宽改造问题,分析了路基在拓宽过程中比较常见的不均匀沉降病害,希望在项目设计阶段就摸清旧路在加宽中路基沉降的变形规律,并提出防止其沉降变形的技术方案,在稳定控制沉降标准的状态下就完成旧路拓宽工程。
The application of the technology of preventing the uneven subsidence of the roadbed can improve the quality of the old road widening project. In this paper,the problem of widening of the old road in urban area is analyzed,and the uneven settlement of subgrade is analyzed,and the deformation law of the old road in the widening of the foundation settlement is proposed.
