拱坝砼标号合理选择的探讨

Rational Choice of Concrete Design Standard for Concrete Arch Dams

本文对砼设计标准，利用砼后期强度以及拱坝应力重分布的特点等方面的综合分析，探 讨了拱坝砼标号的合理选择以及降低拱坝砼个别部位抗压安全系数的合理性，以期获得更经济安 全的拱坝．

Have researched these cases in question and analysed the concrete design standard, the utilization of concrete later strength and the character of stress redistribution. Finally, this paper provides the rational choice of concrete design or arch dams and the rationalization of the safty factor for compression reduction in sereral part of Arch Darn, in order to serve as a basis for more economical and safer concrete arch Dam.
