| 摘 要： | 通过模拟不同的预应力束道上浮弯曲半径，进行了6片试验梁的剥落应力试验。分析得出了影响剥落应力的主要因素有：预应力筋张拉力、束道弯曲半径、束道中心线上下部分的结构刚度等。试验结果表明，试验梁剥落破坏曲线基本上沿波纹管中心线断面破坏。

| Abstract: | By simulating different floating curve radiuses of the prestressing forces way, the experiment on spalling stress is done with six experimental beams. The analysis shows that the main factors which influence the spalling stress are as follows: the stressing force of prestressing bundle, the curve radiuses of the way, the structural rigidity of the center line of the way and etc. The results of the experiments show that the deterioration curve of the balks basically coincides with the center line of the bellows. |
