1、11.船舶总纵强度与扭转强度计算书2005年12月11.一.前言本船为航行于A、B级航区内河船舶，船体结构为混合骨架型（#22-#117甲板和船底为纵骨架式，其他为横骨架式）。本船有一个货舱，大开口范围#25至#112肋位，无舱口盖。船舶主尺度及主要参数如下：总长Loa=72.33m计算船长L=68.82m垂线间长LBP=68.82m型宽B=11.9m型深D=4.2m设计吃水d=3.5m方形系数Cb=0.889水线面系数CW=0.976货舱口宽度b=8.775m货舱口长度l1=45.24m舱壁间距l1H=49.4m装载散货量W=2088.87t本船b/B=

2、0.737和l1/l1H=0.916，属于大开口船，其总纵强度与扭转强度按照《钢质内河船舶入级与建造规范》（2002）和2004年修改通报及《钢质内河船舶船体结构直接计算指南》（2002）对大开口船的规定，校核A、B、C级航区的总纵强度与扭转强度及屈曲强度。二.总纵弯曲外力计算1.载荷工况及重量分布载荷工况及重量分布的数值，见表1。表1各载荷工况及重量分布表工况站距满载出港（A）满载到港（A）满载出港（B、C）满载到港（B、C）空载出港空载到港0—165.63342.93565.63342.93565.63342.9351—243.49343.49343.
