摘　　要：欧洲第三代核电站(European pressurized reactor,EPR)内安全壳建造中大量使用了模块化施工技术,缩短了核电站建造周期、节约了建造成本。以某核电站为工程依托,采用有限元技术,提出了钢衬里焊接残余应力的数值模拟等效方法,考虑了混凝土非线性本构关系和时变效应,分析了钢衬里在焊接残余变形、不均匀温度作用、新浇筑混凝土侧压力及风荷载等施工因素对结构力学性态的影响,得出了钢衬里模块化高度与混凝土一次浇筑最大高度的相关曲线,为EPR内壳模块化施工提供了理论依据。Module construction technology is used to construct Euro third-generation nuclear power plants （European pressurized reactor, EPR） which can greatly shorten construction period and save construction costs. Based on the inner containment of some nuclear power plant engineering, welding residual stress numerical simulation equivalent method is provided for liner. This study by finite element method also analyzes structural mechanical behavior under construction factors, such as concrete nonlinear constitutive relations and time effects, welding residual deformation to liner, uneven temperature effect, pouring concrete lateral pressure and wind loads. This paper finally gives the correlation curves of liner module and concrete pouring maximum height, which provide theoretical basis for module construction of the EPR inner shell.
