摘 要: 应用船体梁理论,对船长型深比L/D大的扁长内河船的外力计算,计入了挠曲修正.用编制的程序对一条L/D=30的模型船及一艘正常尺度范围的3000t驳船进行了计算.两个算例,考虑弯曲挠度影响对静水弯矩的修正量分别为17%和2%.所以对L/D较大的扁长船,其弯矩计算中应考虑计及挠度修正. Taking account of the deflection on bending moment,this paper applies hull's beam theory to make exteral force calculation to inland vessels with large ratio of length to depth.It also provides two calculation examples.One of which is to a model ship with ratio of length to depth being 30,the other is to a 3 000 ton barge within normal dimention.Their corrective quantity of the influence of deflection to bending moment in calm water are respectively 17% and 2%.
