Analysis and Study on Roadbed Deformation of Expansion Split-joint Section in Huizhou-Shenzhen Expressway

道路加宽改造工程完成后,路面常出现纵、横向裂缝等病害,裂缝宽度因路堤高度、地基稳定条件及其性质等变化而不同。针对旧路加宽改建后的病害,分析了旧路加宽工程新旧路路基在沉降、变形和刚度等方面的差异导致的某些特殊病害,有关经验可供相关专业人员参考。

The faults of vertical and transverse cracks often occur on the pavement after the widening reconstruction of the roads.The crack widths are different with the variation of embankment height,subgrade stability and characters.In the light of the faults of the old roads after widened and reconstructed,the article analyzes some special faults led by the difference of the new and old roadbeds in the settlement,deformation and rigidity.The relative experience can be referred for the specialty members.
