摘   要随着世界经济的发展，交通运输业也在持续高速发展，内河运输的地位也越发重要。内河货船作为内河运输的支柱，我国长江、珠江、运河等内河对货船拥有广大的需求，内河造船业迎来了良好的发展机遇。所以船舶经营者和船运公司都在密切关注内河货船的发展状况。  

本次毕业设计的主题就是内河船的结构规范设计，通过已学知识、报刊杂志、网络信息等进行调查研究，对内河货船的构造和特点有了整体认识。然后，仔细阅读已提供的《钢制内河船舶建造规范》(2009版)、型线图和总布置图，结合《船体结构》和《船体制图》形成了完整的设计思路。本船为钢质内河货船，设为单层连续甲板，货船区域的甲板、平台、双层底、双舷侧以及首尾区域的双舷侧均为纵骨架式，首尾以及其它区域舱底均为混合骨架式。 59162

本文研究的内容包括：

1.内河货船的发展、分类、市场以及安全问题，结构设计的概念、方法、步骤等。

2.99.7m内河货船的计算说明书。

3.绘制中横剖面图和基本结构图。

4.完成强度校核。

毕业论文关键词：内河货船；规范设计；中横剖面图；基本结构图；强度校核

Abstract As the world economic development, transportation is also sustained rapid development, the status of IWT is also increasingly important. IWT Inland cargo ship as a pillar of China's Yangtze River, Pearl River, canals and other inland demand for cargo ships have a vast, inland shipbuilding ushered in a good development opportunity. Therefore, ship operators and shipping companies are closely watching the development of inland cargo.

This graduation project is the subject of structural design specification river boat, been through knowledge, newspapers and magazines, network information and other conduct research on the structure and characteristics of inland cargo ships have overall understanding. Then, carefully read the provided "Inland Steel ship construction norms"（2009）, lines plan and general arrangement drawings, combined with "the hull structure" and "Hull Drawing" formed a complete design ideas. The ship is a steel inland cargo, double-side to single continuous deck, deck cargo area, platform, double bottom, double side and end to end regions are longitudinally framed, and the other end to the bilge area are mixed skeleton.

Contents of this paper include:

1. The development of inland cargo, classification, market and security issues, conceptual design, methods, steps, etc.

2.99.7m inland cargo calculation instructions.

3. Draw the basic structure of the cross-sectional view and FIG.

4. Complete the strength check.

Keywords: inland cargo; standard design; in cross-sectional view; basic block diagram; strength check
