摘　　要：以大连港鲶鱼湾港区30万吨级码头工程为实例,详细分析了半潜驳下潜区水深不满足沉箱浮游稳定要求的问题解决方法,并与营口港30万吨级原油码头工程中的解决方法进行对比。实际施工结果表明,起重船助浮大型沉箱半潜驳出运工艺是切实可行的。该方法进一步完善了原有半潜驳出运沉箱工艺的不足,扩展了半潜驳出运沉箱工艺应用范围。Taking the 300 000 ton-class oil terminal engineering of catfish bay in Dalian Port as an example,this paper analyzes the solution for the problem that the largest depth of semi-submersible barge could not meet the request of floating stability of large-scale caisson.A comparison with the method of 300 000 ton-class oil terminal engineering in Yingkou port is made.The result shows that the technology of semi-submersible barge shipping large-scale caisson assisted by crane ship is feasible.This method is an improvement of the original shipping technology for the large-scale caisson and had broadened the appliance field of the semi-submersible barge shipping large-scale caisson.
