In this paper,firstly,the writer imaginarily designs a real single-curvature arch dam. According to similarity theory,model is then made and test in the experimental laboratory.Undamage model is not only simulated,but also crack damage model,which is loaded from jacking apparatus,is mocked,and dynamic characteristics, including primiarily frequency and modal, is tested in all kind of statuses completely.

本文首先设计一座假想的单曲拱坝，然后根据相似理论，在实验室制作模型进行试验，试验不仅模拟了完好状况下的拱坝，而且还通过加载方式较真实的模拟了不同损伤裂缝程度下的拱坝，并且完成了各种不同状况下的动力特性测试，主要是频率和模态。
