Abstract

In this paper, the dynamic response characteristics of an ancient shipwreck “ChangJiangKou II” salvaging system during its salvaging operation, including off-bottom, lifting and off-surface stage, are numerically and experimentally investigated. In order to accurately predict the hydrodynamic performance of “ChangJiangKou II” and the crane barge during the salvaging operation, a specific designed coupled time-domain model combining wreck-soil interaction, lifting module and mooring module is established. A physical model-scale experiment for dynamic lifting of an underwater structure is performed to validate the coupled numerical model. The performance of the dynamic lifting process in different lifting speeds and different environmental conditions is analysed and discussed. The experimental results indicate that there is a tension distribution process during the lifting operation and an external disturbance to the shipwreck can lead to a large increase in lifting cable tensions.

“长江口二号”沉船打捞作业动态响应特性：物理与数值试验

本文对古沉船“长江口II号”打捞系统在离底、吊升和离水面阶段的动态响应特性进行了数值和实验研究。为了准确预测“长江口二号”及起重驳船在打捞过程中的水动力性能，建立了具体设计的结合沉船-土相互作用、起重模块和系泊模块的耦合时域模型。为了验证耦合数值模型的有效性，进行了水下结构动力提升的物理模型尺度实验。对不同提升速度和不同环境条件下动态提升过程的性能进行了分析和讨论。试验结果表明，吊装过程中存在张力分布过程，船体外部扰动会导致吊装索张力大幅增加。
