摘　　要：墩梁固结构造是刚构体系钢轨道梁桥的关键部位。通过比较焊接连接、嵌套式连接、预应力锚栓连接三种墩梁固结构造方案,创新性地提出传力机理可靠、疲劳性能优越、可实施性好的预应力锚栓连接方案,并在此基础上进行锚固构造的锚固能力及预应力锚栓受力验算,以及锚固构造稳定性计算,锚固构造的应力计算,以此指导此类桥梁的设计工作。Due to its good ride comfort and strong span ability, rigid frame bridge with steel track beam has been widely used in straddletype monorail transportation. By comparing the welding connection, nested connection and the connection with pre-stressed anchor bolt,a new connection scheme with pre-stressed anchor bolt has been put for ward which has more reliable power transmission mechanism,superior fatigue performance and better implementation. On the basis of this, the anchorage capacity of the anchorage structure, the stress checking computation of the pre-stressed anchor bolt and the calculation of its stability and stress are carried out. This research can provide guidance for similar bridge design.
