摘　　要：在我国交通基础设施建设大力发展的同时,亟需进行加固或维修的旧桥也越来越多。对于交通量不大但数量众多的农村低等级公路桥梁,问题尤为突出。本文通过对无腹筋UHPC桥梁设计、受力、造价等方面的研究,对无腹筋UHPC桥梁在农村旧桥加固中的应用进行综合性评价。With the development of China s transportation infrastructure construction,there are more and more old bridges in urgent need of reinforcement or maintenance.For the rural low-grade highway bridges with small traffic volume but large number,the problem is particularly prominent.Through the research on the design,stress and cost of UHPC bridge without stirrups and bent-up reinforce bar,the application of UHPC bridge in the reinforcement of old rural bridges is comprehensively evaluated.
