近代双联挖泥船在河湖与近海等宽水域中疏浚施工作业时，通常会遭遇风成波浪的强力振动，从而存在作业船只与水面风成波浪发生共振的可能性，客观上存在施工作业风险．为避免这种风险，文章针对水面重力线性波，利用理想流体的势流理论进行理论分析，得出重力线性波波动频率的计算公式，并根据作业环境条件进行具体的频率计算，与双联挖泥船的固有频率进行比较，得出施工安全的结论．
近代雙聯挖泥船在河湖與近海等寬水域中疏浚施工作業時，通常會遭遇風成波浪的彊力振動，從而存在作業船隻與水麵風成波浪髮生共振的可能性，客觀上存在施工作業風險．為避免這種風險，文章針對水麵重力線性波，利用理想流體的勢流理論進行理論分析，得齣重力線性波波動頻率的計算公式，併根據作業環境條件進行具體的頻率計算，與雙聯挖泥船的固有頻率進行比較，得齣施工安全的結論．

Strong vibration caused by waves is quiet common when modern double dredgers operate on wide waters or coast, resulting in resonance risk between constructing ships and wind waves. The fluctuation frequency formula of gravity linear waves is talked about in this article, based on the analysis of gravity linear waves in water and the potential flow theory of ideal fluid. The particular frequency computing approach is also detailed according to real working environment, and the security of construction can be ensured after the comparison of the inherent frequency of double dredgers with the fluctuation frequency of gravity linear waves.
