摘　　要：相似结构模型试验研究时,必须合理把握基本相似关系,这既是模型设计的根本依据,也是由试验结果反推原型结构性能的有效途径。但是由于模型材料的限制和制作模型结构时产生的一些施工误差,使得实际模型与原型的相似关系并不满足设计模型结构时理论所要求的相似关系。这时需要合理调整相似关系,以使模型试验的结果能比较准确地反推到原型。给出了依据材性试验结果调整相似关系的方法,探讨该方法对试验结果的影响,分析现存的问题,并给出一些建议。In the model structure test, similarity must be fixed reasonably, which is the most fundamental theory for model structure design, and the most essential way to trace back to the performance of prototype structures. However, because of the limit of materials and the deviation caused by construction, the similarity between the true model and prototype usually does not meet the design requirements. Under this situation, it is necessary to reestablish the similarity to get more accurate results to reflect the behavior of the prototype. Simi- larity adjustment approaches based on material properties was studied. The approaches of similarity adjustment based on material properties, how the disturbance of similarity influence on the results of the test, the existing problems, and some suggestions were presented.
