摘　　要：以某一深海平台的两种不同的水深截断系泊缆为例,采用模型试验和数值计算结合的方法研究了单根系泊缆的阻尼特性,并采用不规则波模型试验予以验证。结果表明,通过调节系泊缆参数可使水深截断系泊缆的波频阻尼与全水深系泊缆一致,由于截断较大,其低频阻尼虽有增加,但仍然显著小于全水深系泊缆。Using the deepwater platform with two different truncated mooring lines as an example. Damping of the single mooring lines is investigated by means of model test and numerical simulation and is verified by irregular wave model tests. The result shows that wave frequency damping can be consisted with truncated mooring line by adjusting the parameters. But the low frequency damping of truncated one is obviously smaller than full-depth one if the truncation is large.
