摘　　要：以T/CHTS 10066—2022《公路桥梁超高性能混凝土加固技术指南》为研究依托,结合实际工程中出现的对桥梁抗弯承载力有影响的病害,研究了在不改变截面高度和增加截面高度两种条件下,对截面抗弯承载能力的影响,并分析了各种影响因素对抗弯承载能力影响中所占的比重。Based on the group standard T/CHTS 10066—2022“Technical Specification for Strengthening Bridge with Ultra-High Performance Concrete”,flexural capacity of reinforced concrete beams with UHPC is studied in change section height and keep section height conditions.Meanwhile,proportions in impacting flexural capacity factors are analyzed combining with influencing flexural capacity bridge diseases in engineering.

关 键 词：桥梁加固 UHPC 抗弯承载能力
