| 摘 要： | 选取有代表性的各种跨径的简支梁桥标准图,对这些简支梁进行弯矩、挠度计算分析,用MATLAB编制了数据处理程序,得出由荷载变化而引起挠度变化的内在规律,提出了基于静载挠度来快速实现既有桥梁承载能力评定的分析方法。

| Abstract: | bending moment LAB, the paper the fast analysis The paper chooses the standard drawings of typical simple-supported beams and carries out and deflection calculation and analysis. With the data processing program worked out by MAT- finds out the inherent law of deflection changes caused by load changes and further puts forward method on carrying capacity of existing bridges based on static load deflection. |

| Keywords: | simply-supported beam bridge bending moment deflection carrying capacity |
