随着我国高速铁路的快速发展，针对高速铁路中桥梁的损伤识别研究已成为热门领域。通过曲率模态理论对实体单元建立的混凝土箱梁有限元模型进行损伤识别可行性研究，分析不同损伤位置、损伤程度和测点位置条件下损伤指标的变化。结果表明，结合曲率模态理论方法和实体单元建模方法可以更加全面准确地对损伤结构进行识别，为今后高速铁路桥梁检测提供参考。

With the rapid development of the high-speed railway, the damage identification study of high-speed railway bridges has become a hot research topic. In this paper, the feasibility study is made on damage identification of the finite element model of the reinforced concrete box girder using solid elements by curvature model theory. An analysis is made of the variation of damage factors with the changes in damage locations, damage degrees and the positions of measuring points. The results show that structure damage can be identified more accurately and comprehensively with the application of curvature model theory with solid elements. It provides a reference for the detection of high-speed railway bridges in the future.
