填方路基及桥梁加宽拼接技术探讨

Discussion on Subgrade and Bridge Widening Splicing Technology

高速公路扩建过程中,由于新老路基的沉降与桥梁的沉降存在不均匀的现象,导致填方路基与桥梁拼接施工的部位产生纵向裂缝。论文结合施工经验与工程实例,在满足填方路基与桥梁拼接的施工原则上,对施工过程中的拼接技术进行了详细的分析,以供参考。

Highway expansion process, due to the new and old roadbed settlement with the bridge settlement exists the phenomenon of uneven, resulting in filling roadbed and Bridge concatenation construction parts of the longitudinal cracks.Combined with engineering experience and example, to meet the filling roadbed and Bridge concatenation construction principle,splicing technology in the construction process of the detailed analysis, for reference.
