摘　　要：结合我国渤海锦州9-3油田新建导管架平台的实际工程背景,针对大型浮托安装驳船在极浅水条件下运动性能和触底现象开展数值计算和物理实验研究。通过两者之间的相互对比,验证了计算结果的正确性。实验中观察到驳船的浅水效应现象,并对该现象的产生原因进行了分析。结合实际海域的海洋环境条件,开展敏感性分析,得到驳船在不同海况下的运动特性,并对驳船是否会发生触底进行了评估。研究结果为保障极浅水条件下,导管架组块浮托安装实际工程的安全应用提供了有力支撑。To support the floatover installation of a newly developed jacket platform of the JZ9-3 oil field in China Bohai Bay,numerical simulations and physical experiments were undertaken to investigate the mo鄄tion response and possible bottom grounding of the large floatover barge moored in extremely shallow wa鄄ter.Significant shallow water effect was observed in the physical model test.Sensitivity studies were car鄄ried out to obtain the motion response characteristics of the barge in different sea states.Evaluation of the risk of the barge爷s bottom grounding was conducted.The practical engineering applications in ultra-shallow wa鄄ter will thus be guaranteed by the present numerical and experimental investigations.
