大水深链斗式挖泥船斗桥的设计

Design of Ladder for Bucket Dredger Working in Deepwater Area

斗桥设计是链斗式挖泥船设计过程中的一项重要工作,对于作业于深水区的链斗式挖泥船,其斗桥尺度大,特别是长度与宽度之比很大,在作业过程中的强度和刚度问题较为突出。本文主要研究了大水深链斗式挖泥船的斗桥设计方法,参考《钢结构设计规范》中对箱型梁的规定,并结合挖泥船实际工作对斗桥的要求来确定斗桥的主要尺度和结构布置。

The bucket ladder design is important in the design of bucket dredger. With large dimensions, particularly in the ratio of the length and the width, the ladder of bucket dredger working in deepwater area is faced with prominent strength problems during different operating conditions. This Paper mainly studies the ladder design method of bucket dreger working in deepwater area. The principal dimensions are determined by reference to the regulations on box girders in Design Code for Steel Structures and combined with the dreger＇s actual work reqiurements.
