摘要
基于附加质量模型的缺陷,提出了附加质量折半模型,采用该模型分析了拱坝的自振特性,并与原计算模型试验结果作了对比分析,结果表明:相对于附加质量模型,附加质量折半模型计算所得的坝体自振频率更符合实际,但偏差仍相对较大。
Based on defects of additional quality model,the paper puts forward additional quality binary model,analyzes the arch dam self-vibration properties by applying the additional quality binary model,and makes a comparison with original calculation model. Results show that： comparing to additional quality model,the dam self-vibration frequency calculated with additional quality binary model better meets practice. However,it has larger deviation.
