钢板混凝土结构性能优越,在民用建筑、桥梁、隧道等工程中得到了越来越广泛的应用。当应用于核电厂时,钢板混凝土结构在受力特点、功能需求和施工建造方面表现出较强的特殊性,近年来国内外已经开展了大量钢板混凝土在核电厂工程中的应用研究,形成了较为完整的规范体系。文章对钢板混凝土结构在核电厂工程中的应用与研究现状进行综述,包括相关的结构设计规范情况、典型的结构构造形式、基本构件和单元力学性能及设计方法、特殊工况下(事故工况、大飞机撞击等)结构性能与设计方法。并针对核电厂特殊功能需求以及精细化设计建造方面的要求,提出了需要进一步研究的问题,包括各类型钢板混凝土基本单元的复杂静力性能试验;钢板混凝土结构在特殊工况下的受力性能和设计条件;合理简单的构造方式;模块加工精度、混凝土浇筑温度和模块变形控制、混凝土浇筑密实度和质量控制等关键建造技术。
Steel-plate concrete structure has excellent performance,and has been more and more widely used in buildings,bridges,tunnels and other projects.When applied to nuclear power plants,steel-plate concrete structure shows strong particularity in terms of the stress characteristics,functional requirements and construction.In recent years,a large number of application studies of steel-plate concrete structure in nuclear power plant engineering have been carried out at home and abroad,forming a relatively complete specification system.In the paper,the application and research of steel-plate concrete structure in nuclear power plant engineering were reviewed,including relevant structural design specifications,typical structural forms,mechanical properties and design methods of basic components and units,structural properties and design methods under special working conditions(accident conditions,large aircraft impact,etc.).Finally,according to the special functional requirements of nuclear power plants and the requirements of fine design and construction,the problems that need to be further studied were put forward,including the complex static performance test of various types of steel-plate concrete elements;the mechanical properties and design conditions of steel-plate concrete structure under special working conditions;reasonable and simple structural details,some key construction techniques such as module machining precision,concrete casting temperature and module deformation control,as well as concrete casting compactness and quality control.
