［摘要］基于《核电厂混凝土结构技术标准》（送审稿）和美国规范ACI 349-3，对比分析了中国和美国核安全相关混凝土结构构件层次的安全度。结果表明，中国核电厂技术标准轴心受拉、受弯、轴心受压、偏心受压、受剪和受扭钢筋混凝土构件的安全度与美国规范ACI 349-13相当，受冲切构件的安全度比美国规范ACI 349-13高约30%，局部受压构件的安全度比美国规范ACI 349-13高约45%，深梁的安全度与美国规范ACI 349-13相当；牛腿按简化方法设计时的安全度比美国规范ACI 349-13低约20%，按拉压杆模型设计时的与美国规范ACI 349-13相当。中国核电厂技术标准轴心受拉、受弯预应力混凝土构件的安全度分别比美国规范ACI 349-13高约10%和15%，预应力混凝土受剪构件的安全度与美国规范ACI 349-13相当。

Abstract:A comparative analysis is made for the safety of nuclear safety related concrete structures based on  Technical standards for concrete structures in nuclear power plants (Manuscript) and American code ACI 349-13. It is revealed that the safety of reinforced concrete members in axial tension, bending, axial compression, eccentric compression, shear and torsion designed according to Chinese code and American code ACI 349-13 are essentially identical. The safety of reinforced concrete members in punching shear designed based on Chinese code is 30% greater than that based on American code ACI 349-13, and the safety of  the members in local compression is 45% greater than that based on American code ACI 349-13. The safety of deep beams in Chinese code and American code ACI 349-13 is coincident. The safety of corbels designed by simplified method in American code ACI 349-13 is 20% greater than that in Chinese code, and is coincident to the American code  ACI 349-13 using stud and tie model. The safety of prestressed concrete members in axial tension and bending designed based on Chinese code is 10% and 15% greater than that based on American code ACI 349-13, and the safety of the members in shear designed by both codes are coincident.
