摘要
分离式加筋土桥台不同于传统加筋土挡墙结构,主要应用于路桥连接过渡段,具有施工便捷、收坡减跨、节省造价以及低碳环保的特征。文中主要介绍了分离式加筋土桥台结构特点及其与传统加筋土挡墙结构的不同,最后结合工程案例,探讨了分离式加筋土桥台施工工序及控制要点。结果表明,分离式加筋土桥台在实际工程中不仅可以很好地解决收坡减跨、空间占用的问题,也具有良好的景观效果,较好地满足了高速公路高质量建设的要求,可为类似工程设计与建设提供借鉴。
Different from the traditional reinforced soil retaining wall,disconnect-type reinforced soil(DRS)abutment was mainly used in the bridge-subgrade transition section with significant features of convenient construction,span reduction,cost saving,and low-carbon emissions.This paper mainly introduced the structural characteristics of DRS abutment and its differences compared to the traditional reinforced soil retaining wall.In addition,a case study with disconnect-type reinforced soil abutment was analyzed to illustrate the construction process and control points.The results indicated that the DRS abutment could not only effectively save land and reduce space occupation in practical engineering,but also had good landscape effects.This type of abutment could meet the requirements of high-quality construction on highways,and providing guidance and reference for similar engineering design and construction in the future.
