摘要/Abstract

摘要：

以“长江口二号”沉船整体打捞作业为背景,设计相应的打捞方案,并对其关键状态的动力响应进行数值实验,综合分析不同海况下多体耦合系统运动响应特性及缆绳受力情况.研究结果表明,横浪工况下,打捞系统的不稳定性增加,作业风险明显高于其他浪向的同浪级工况.此外,沉船离底状态下,提升缆及系泊缆的张力响应极值会高于沉船部分出水时的受力情况.该数值实验验证了打捞方案实施的可行性,同时为规避打捞作业风险的海况决策提供了重要依据.

Abstract:

A wreck salvage scheme is designed for the integral salvage of “Yangtze River Estuary II” ancient ship, and the dynamic response of the critical state of salvage is investigated via numerical simulation. Comprehensive studies including the motion response characteristics of the multi-body coupling system and the tension of the cable under different sea conditions are conducted. The results show that the instability of the salvage system increases under the transverse sea condition, and the operation risk is obviously higher than other waves of the same wave level conditions. In addition, the tension responses of lifting cables and mooring cables are higher in the off-bottom stage than that of the submerged part of the wreck. The numerical results demonstrate the feasibility of the salvage scheme, providing reference for decision-making on sea conditions to avoid the risk of salvage operation.

Key words: wreck salvage, coupling system, numerical simulation, dynamic response
