摘　　要：工程船舶由近岸施工逐渐走向外海施工,然而非洲和拉丁美洲的一些国家海域波浪周期较大,对工程船舶安全作业带来很大困难。通过物理模型试验,系统研究了打桩船在涌浪长周期波作用下的动态响应,给出船舶运动量随波浪的变化规律,特别是波浪周期接近船舶自振周期或锚泊系统自振周期时,船舶的运动量增大明显。有关研究成果可为打桩船外海作业特别是涌浪长周期波海域施工作业提供技术参考和支撑。The construction of engineering vessel from near shore to offshore construction, however, in the Africa and Latin America coastal area, wave period is relatively long, which cause difficulty to engineering vessels construction safety. Through physical model test, we systematically studied on the dynamic response of pile driving vessel under swell and long period wave,given the variation rule of the vessel＇s movement with the wave, especially when wave period is close to vessel natural vibration period or vessel mooring system natural vibration period, the movement of vessel is significantly increased. Research results of this paper can provide technical guidance and support to pile driving vessel construction work in offshore, especially for the construction of swell and long period wave sea area.
