寒区新旧煤矸石路基结合部不均匀沉降研究

The Research on Junction of Subgrade of Coal Gangue about the Differential Settlement in Cold Region

在寒区煤矸石公路路基拓宽中如何将新旧煤矸石路基良好的拼接在一起是工程上关注的热点问题,文章对新老煤矸石路基沉降机理进行分析,针对路基结合部位沉降的原因,提出防止煤矸石路基结合部差异沉降的常用处理方法,为寒区煤矸石公路路基拓宽工程施工提供参考。

Coal gangue as waste to the characteristics of its low cost, high benefit, environmentally friendly, more and more applied in highway roadbed. In cold regions, how to join the new and old road of coal gangue together is a hot problem which many project will focus on it. In this paper, the causing the old and new embankment settlement mechanism were analyzed. According to reasons which cause the differential settlement of the joint part of subgrade of coal gangue, proposed common approach to prevent the junction of gangue differential settlement of subgrade. Provide a reference for highway subgrade of coal gangue widening in cold regions.
