[摘要] 结合已建成的几座工程实例，介绍了造船工业厂房屋架常用的几种结构形式：平面桁架、空间桁架以及网架结构。通过不同屋盖的结构体系、受力特性、应用优缺点及对工程成本的比较，提出不同结构的选型方案。同时，对不同结构形式屋盖的施工方法作了进一步阐述，并以实际工程为例，提出新型滑移平台高空施工法的思路和方法，以供同类结构施工时参考。

Abstract: Based on some built-projects, the roof truss structure form features of factory building in shipbuilding industry were introduced, such as plane truss, space truss and space grid structures.  The difference scheme of choosing description of structural system, mechanical properties, merits and faults application in engineering and the building cost was proposed. Construction method of roof truss structure was further discussed. Through practical instances, the lugh level sliding construction of the grid structure roof, some new thoughts were also given, which can be reference for similar projects.
Keywords: plane truss; space truss; space grid structure; high level sliding construction
