| 摘 要： | 根据无粘结部分预应力混凝土梁的受力特点，采用弯矩-曲率法计算无粘结预应力钢筋的极限应力，计算结果与现有的试验数据符合得较好。建立了系统的无粘结部分预应力混凝土简支空心板梁桥设计理论和方法，有助于UPPC梁桥设计理论的完善及发展，并为“公桥规”的修订和完善提供有益的参考。

| Abstract: | According to the bearing characteristic of unbounded partial prestressed concrete beam, this paper using moment curvature method to calculate its ultimate prestressed. It is proved that the results accord with test data. The systemic design theory and method of unbounded partial prestressed concrete bridge with simple hollow board beam is founded in this paper, which can perfect the design theory of UPPC bridge and provide benefit reference for editing the road and bridge criterion. |
