| 摘 要： | 模型试验是研究结构受力性能的有效方法。本文对在车轮荷载作用下,两种不同边界条件的微弯板进行模型试验研究,探讨不同边界条件下微弯板的受力性能。试验结果表明,有无侧向约束是影响微弯板受力性能的重要因素之一;在旧桥微弯板板底中尽管存有一些开裂现象,但仍可继续使用。

| Abstract: | Model testing is an effective method for understanding the behavior and fundamental characteristics of a slab with slightly curved bottom.The two model slabs bearing wheel load under different boundary conditions were tested,in order to investigate the behavior of the slabs under different boundary conditions.The results show that lateral restriction is one of the most important factors for the behavior of a slab with slightly curved bottom,and the cracking slab could be in service. |
