【摘要】 根据收集到的国内外相关规范,通过比较分析国内外水工混凝土结构设计规范,并参照其他相关行业的结构设计规范,对规范中的极限状态设计表达式中的分项系数的确定方法和取值方案进行探讨,发现大部分都是基于可靠度理念进行结构设计,并且国内现行的规范中极限状态设计表达式中的分项系数的确定方法和国外规范推荐的方法十分相近,但取值却存在差异。结合现行规范取用分项系数的方法,并比较其利弊,对于分项系数的取值提出合理的修改建议,可供重力坝结构设计时参考。更多还原

【Abstract】 According to the collected relevant codes at home and abroad,a comparison is made between domestic and foreign codes in hydraulic concrete structural design.By referring to structural design codes of other related industries,this paper discusses the methods and values of partial factors for limit state design expression in codes,.It has been found that limit state design expression is mainly based on the reliability for structural design,and the methods for structural design are very similar in domestic and foreign codes,but the values of partial factors are different.A more rational proposed project for partial factors is put forward to offer a reference for gravity dam structure design.更多还原
