摘　　要：针对全回转式浮吊船拖航横浪工况,运用直接计算方法来分析起重机下船体结构强度,并与规范简化受力下的船体结构强度相比较。结论表明,船体结构在满足规范受力的情况下,结构强度有一定的富裕,船体结构偏安全。The structural strength of the under-crane part of hull is analyzed with direct calculation method under the most critical condition when the crane barge is towing in beam sea. The calculated result is compared to the strength requirements under standard force conditions specified by the Rules. The calculation shows that the hull under crane is safe under the standard con ditions.
