【摘要】 《水工混凝土结构设计规范》（送审稿）采用了概率极限状态设计法，以可靠指标度量结构构件的可靠度，采用分项系数设计表达式进行设计，以代替现行《水工钢筋混凝土结构设计规范（SDJ20-78）》采用的半经验半概率的极限状态设计法和单一安全系数设计表达式．本文介绍了其中材料性能指标的修订方案．更多还原

【Abstract】 The probabilistic limit states design method is adopted in "Design Specifications for Hydraulic Concrete Structure of P. R. China (manuscript to be examined)". In the specifications, the reliability index is used for measuring the reliability of structural members, the design expression of the partial coefficients is used to design. Then the limit states design method of half experience and half probability and the design expression of single safety coefficient of current "Design Specifications of Hydraulic Reinforced Concrete Structure of P. R. China (SDJ 20- 78)" are superseded by the above-mentioned revision measures. Therefore, the revision scheme for the indices of material properties in the specifications (manuscript to be examined) is mainly introduced in this paper.更多还原
