摘　　要：对长江航运有代表性的1000t和2000t大开口分节驳的结构强度进行了实船试验、模型试验、全船有限元分析以及薄壁梁理论计算等全面研究,表明全船有限元分析可作为设计依据,应用薄壁梁的弯扭理论计算该类船中部的应力,精度能满足工程要求。In this paper, the structural strength of 1000t and 2000t integrated barges with long hatch opening, which are the typical vehicles in the Chang Jiang River, are studied by means/of full-scale tests, shipmodel tests, finite element method, and thin-wailed beam theory. Comparison of calculation results with test data has shown that the FEM analysis is well suitable in ship structural design, while the bending-torsion theory of thin-walled beam can only be used to calculate the stresses at the middle part of the ship.
