目前，我国的大机组主厂房主要有３种结构形式：钢筋混凝土结构、钢结构和钢－混凝土组合结构。它们各有不同的特点和存在的问题。此外，随着高强度钢筋和混凝土的研制，高效预应力混凝土结构在工程中的应用范围也有所扩大。主厂房布置形式的改变必将冲击土建结构设计，提出很多新的研究课题。
At present, there are mainly three kinds of structural forms in the main plant of large units in China: reinforced concrete structures, steel structures, and steel-concrete composite structures. They have different characteristics and problems. In addition, with the development of high-strength steel bars and concrete, the scope of application of high-efficiency prestressed concrete structures in the project has also been expanded. Changes in the layout of the main plant will inevitably impact the design of civil structures and put forward many new research topics.
