摘　　要：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。More attention is now paid to analysis and assessment of load carrying capacity of the existing highway bridges in engineering circles. With a quiescent load and racking load test, the strength, stiffness and resistance to crack of the bridge are analyzed. In the practical working conditions, the load carrying capacity of the bridge is properly assessed. It is of practical value to comprehensive appraisal of bridges.
