由于受内河航道条件限制，新研制的江海直达船换代船型的型宽型深比 B/D 大于2.5，船型较为宽扁，这种超规范江海直达船的研发面临很多新的挑战，船舶由江入海，环境载荷变化较大，波浪砰击、波激载荷及船舶振动较为严重，另外，由于江海直达船船型较海船更为扁平，球艏及底部更易受到砰击载荷作用。经分析后确定采取分段船模的方法开展江海直达船在典型装载(满载和压载)工况下的模型试验研究，在规则和不规则波极限工况下进行船体梁的垂向弯曲特性与波激、砰击振动响应预报研究。研究表明，在某些工况下江海直达船的波激、砰击响应较大。

A new generation of river-to-sea ship is developing. Due to the restriction of the waterway, ratio of breadth to depth of the new ship is out the limitation of 2.5, which is the maximum in CCS’ river-to-sea ship standard at present. This means that the ship’s form is wide and flat. Subsection model tests of the river-to-sea ship are established and carried out under ballast condition and fully loaded condition respectively. Based on the test results it is revealed that under several particular conditions, river-to-sea ship will suffer from tremendous wave induced loads and slamming loads under several particular conditions.
