摘　　要：新老路结合部如果施工处治不当,容易产生工后不均匀沉降,致使结合部出现纵向裂缝、横向滑移、路面不均匀沉降等病害。从技术准备、新老路边坡土方利用翻挖压实、挖土质台阶、土工格栅处治、接长侧涵洞施工等5个方面论述了安楚高速公路新老路结合部施工技术。Typical method of highway reconstruction is one or both side-widen, unsuitable construction methods of conjoint section shall lead to troubles like subsidence, longitudinal cracks, tranverse slippage and so on, especially, in re-construct highway project in high mountain area, which owns complicated hydrology and geology conditions. Take Anchu Expressway Reconstruction Project as example, the article details the construction technology of cojoint section by technical preparation, re-use of side slope soil, soil step excavation, earthworks grille treatment, longed part construction of culvert.
