摘要
结合工程实例研究了道岔区线路加固特点,为减小道岔区线路加固纵横梁连接结构的运营期变形,提出了上下扁担梁加预应力钢筋连接方案,对该纵横梁连接方案的结构设计方法进行了研究,为同类项目提供参考。
Combining with the engineering examples,this paper researched the reinforcement characteristics of turnout line,in order to reduce the operation deformation of longitudinal and transverse connection structures of turnout area operation,proposed the connection scheme of adding prestressed steel bars to the upper and lower carrying pole beams,the researched structural design method of longitudinal and transverse beam connection scheme,provided reference for similar projects.
