水中悬浮隧道通过系泊系统使其悬浮在水下一定深度处，与潜器的碰撞可能会使隧道结构产生较大运动响应，呈现大幅度的非线性位移，会使隧道失去原有的稳定性甚至对隧道安全性产生较大的影响。因此，本文开展考虑多场耦合场景下碰撞载荷作用下，水中悬浮隧道的运动响应研究。通过与文献中试验结果的对比分析，验证数值模型的有效性。建立水中悬浮隧道及其系泊系统的三维运动模型，同时通过Abaqus建立水中悬浮隧道的碰撞场景与STAR-CCM+进行双向耦合联合仿真，开展水中悬浮隧道被潜器撞击后的运动响应研究，并分析不同碰撞场景下水中悬浮隧道的运动响应变化规律。
A submerged floating tunnel (SFT) is suspended at a certain depth underwater through the mooring system, and the collision with the submarine may cause the tunnel structure to produce a great motion response, presenting a large nonlinear displacement, which will make the tunnel lose its original stability and even have a great impact on the tunnel safety. Therefore, this paper studied the motion response of SFT under the action of collision load in a multi-field coupling scenario. The effectiveness of the numerical model was verified by comparative analysis with experimental results in the literature, and the three-dimensional motion model of SFT and its mooring system was established, at the same time the collision scene of SFT by Abaqus was established, and STAR-CCM+ bidirectional coupling joint simulation was carried out, The motion response of SFT impacted by submarine was studied, and the variation law of motion response of SFT under different collision scenarios was analyzed.
