现有公路桥梁承载力的分析与评定是当前工程界非常重视的问题。文章通过桥梁的静、 动载试验研究，结合桥梁的实际工作状态，全面地分析桥梁的挠度、刚度、抗裂性，准确评定桥梁 的现有承载力，这对于公路桥梁的综合评定具有一定的实用价值。
The analysis and assessment of the bearing capacity of the existing highway bridges are the problems that the engineering community attaches great importance to. Through the static and dynamic tests of the bridge and the actual working conditions of the bridge, the paper comprehensively analyzes the deflection, stiffness and crack resistance of the bridge and accurately evaluates the existing bearing capacity of the bridge. This method has a certain value for the comprehensive evaluation of the highway bridge Practical value.
