摘　　要：[目的]为解决礁石区域搁浅船舶难以通过过底钢丝绳进行浮箱绑扎的问题,[方法]以某搁浅船救助为例,使用打捞作业专用分析软件GHS进行搁浅船浮态分析,将GHS计算浮态结果作为浮箱及桁架结构校核的输入条件,使用ABAQUS软件进行固定浮箱桁架结构及浮箱箱体的结构分析。[结果]结果表明:难船出浅浮态可控制在横倾5°以内,桁架及浮箱结构满足应力要求。[结论]研究成果可为搁浅船舶出浅提供一定参考。[Purpose]To solve the problem of stranded ships in reef areas being difficult to tie up their floating tanks with bottom wire ropes,[Method]taking the rescue of a stranded ship as an example,GHS,a specialized analysis software for salvage operations is used to analyze the floating state of the stranded ship.The calculated floating state results of GHS are used as input conditions for the verification of the floating tank and truss structure,and ABAQUS software is used for the structural analysis of the fixed floating tank truss structure and floating tank body.[Result]The results indicate that the shallow floating state of the difficult ship can be controlled within a lateral tilt of 5°,and the truss and floating tank structures meet the stress requirements.[Conclusion]The research results can provide some references for stranded ships to remove from grounding position,
