摘　　要：基于沉船打捞离底阶段的动力响应时域模拟,提出了一种针对该阶段的半定量安全性评估方法.该方法旨在统括打捞母船的各运动模态,提供对沉船打捞系统在不同海况下工作时的整体安全性评价分数.以“长江口二号”打捞项目为依托,进行了不同浪向角下的系统动力响应敏感性分析,最终得出(150°,210°)和(330°,30°)两个波浪入射角区间是比较理想的打捞作业窗口.Based on the time domain simulation of the dynamic response of the wreck salvage system in the off-bottom stage,this paper proposes a semi-quantitative safety assessment method for this process,aiming to summarize all motion modes of the salvaging mother ship and provide overall safety assessment scores of the wreck salvage system under different sea conditions.Based on the“Changjiang Kou 2”project,the sensitivity analysis of the system dynamic response under different wave direction angles is conducted.It is concluded that the two wave direction intervals(150°,210°)and(330°,30°)are relatively ideal salvage operation windows.
