[提要]  结合两个工程实例，介绍了现浇预应力混凝土桁架在框架结构中的应用，总结了预应力混凝土桁架
结构设计与施工的经验与体会，为今后预应力混凝土桁架在大跨度、长悬臂结构中的应用积累了经验。
[关键词]  预应力混凝土  桁架  大跨度  悬挑桁架  有粘结预应力混凝土  后张法

Based on two engineering examples, the application of in-situ prestressed concrete truss in the frame structure is introduced. The experience of design and construction of prestressed concrete truss in the long-span and cantilever can be used for referenced to the similar projects.
Keywords:  prestressed concrete truss; large span; cantilever truss; post-tensioned bonding concrete
