道路桥梁工程中沉降段路基路面施工技术探讨

Discussion on construction technology of subgradeand pavement in settlement section of roadand bridge engineering

以北京至乌鲁木齐国家高速公路山西段道路桥梁工程为例,从桥头沉降段的具体设计结构以及桥台背路堤的压实度、桥头引道地基处的现存设计问题切入,对引出路桥沉降段中路基路面的深层原因展开了详尽的分析,然后对路桥建设中沉降段内路基路面的可用施工技术加以阐述,继而保障好道路桥梁总体上的施工质量。

Taking the road and bridge engineering of Shanxi section of Beijing-Urumqi National Expressway as an example,starting from the concrete design structure of the settlement section at the bridge head,the compactness of the embankment at the back of the abutment and the existing design problems at the foundation of the approach road at the bridge head,the deep causes of the roadbed and pavement in the settlement section of the approach bridge are analyzed in detail,and then the available construction technology of the roadbed and pavement in the settlement section of the road and bridge construction is elaborated,so as to guarantee the road and bridge as a whole.Construction quality.
