中文摘要：

为了对南京明代石拱桥襟湖桥的科学保护技术进行系统研究，首先通过现场调研，对南京明代石拱桥的残损进行分析，找出其可见的病害。然后通过ANSYS有限元模拟分析其结构性能，找出其潜在的病害，并进行结构构件的重要性分析。最后，综合残损调研及数值模拟结果，提出了适用于明代石拱桥的保护技术，得出的结论可供同类型石拱桥的加固修缮参考。

英文摘要：

A systematic study of the conservation technology was done with the aim of protecting a Ming Dynasty stone arch bridge, the Jin Hu Bridge, in Nanjing. First, based on an on -site survey of Jin Hu Bridge, a preliminary analysis of the damage was done to Jin Hu Bridge and the visible causes of this damage. Then, the hidden structural safety hazards and the importance of various structural parts were studied using the ANSYS finite element method, a structural performance simulation analysis. Finally, simulation results were combined with on - site damage survey to propose a suitable conservation plan for protecting Ming Dynasty stone bridge. The results obtained can be applied to the repair and enhancement of similar ancient stone bridges.
