通过一座高速公路上的上跨天桥设计，提出了设置小边跨的无缝连续梁桥内力分析的处理方法，选择了桥台与基础、桥台与梁端的合理连接方式，并进行了有效的构造处理。对无缝桥梁的推广应用提出了存在的问题。 Through the design of an overpass on a highway, a method to deal with the internal force analysis of the seamless continuous beam with a small span is put forward. The reasonable connection between the abutment, foundation, abutment and beam ends is selected and the effective Construction process. The existing problems of the popularization and application of seamless bridges are put forward.
