| 摘 要： | 通过有限元分析较深入地探讨了在不同边界条件下微弯板的受力性能,结果显示保证微弯板有横桥向侧向约束是保证微弯板承载潜力充分发挥的最重要条件之一.因此使微弯板与拱片牢固结合,并加强拱片间横向联系是有效措施之一.

| Abstract: | This paper discusses the performance of load bearing of slab with slightly curved bottom under different boundary conditions by the finite element analysis. The transverse restriction of the supporting surface is the most important factor that affects load bearing capacity of the slab. Finally, some suggestions of strengthening the slab are put forward. |
