摘　　要：超限车过桥的承载力评估是对桥梁加固处理、确保顺利运输的重要保证。该文以广东省上世纪八十年代修建的某跨径为25m的装配式预应力混凝土T梁桥为例,考虑旧桥检算系数Z1和预应力损失,对559t超限车过桥进行承载力评估。The evaluation on the loading capacity of the over-limit vehicles passing bridge is the important guarantee for reinforcing treatment of bridge and ensuring the smooth transportation. Taking an assembly pre-stressed concrete T-beam bridge with 25-m span built in 1980s in Guangdong Province as an example and considering the old bridge check coefficient Z1 and the pre-stressing loss, the article evaluates the loading capacity of 559t over-limit vehicles passing bridge.

关 键 词：超限车 梁桥 承载力 旧桥检算系数
