Abstract: The way of inspection and evaluation of load-bearing capacity of active-duty highway girder bridge was introduced． The proposed approach adopted the sub-calculation factor to modify the expression of the limit state design method to carry out the capacity assessment according to the bridge test results，which improves the objectivity of assessment and operability of evaluation of load-bearing capacity of girder bridge．

Key words: highway concrete girder bridge, carrying capacity, detection assessment, bridge inspection, calculation coefficients

摘要： 介绍了新规范下现役公路混凝土梁桥承载能力检测评定办法。该办法主要是根据桥梁检测结果，采用引入分 项检算系数修正极限状态设计表达式的方法进行承载力评定，提高了桥梁承载力评定客观性和可操作性。
