混凝土耐久性新旧设计标准比较分析

Comparison and analysis of design standard for concrete durability

目前,GB50010—2002《混凝土结构设计规范》中的耐久性规定并不能够满足结构设计使用年限的要求。指导性技术文件CCES 01—2004《混凝土耐久性设计与施工指南》的修订及实施,对于提高我国混凝土结构的耐久性有现实的重要意义。为保证《混凝土耐久性设计与施工指南》更好的实施,就《混凝土结构设计规范》二类环境类别与《混凝土耐久性设计与施工指南》中对应环境作用等级之间的主要差异以表格的形式一一列出对比分析,以供设计参考。

At present,the durability stipulation in＂Code for Design of Concrete Structures＂（ GB 50010-2002 in China） can＇t meet the requirement of design service life of structures.Revision and implementation of ＂Guide to Durability Design and Construction of Concrete Structures＂ （CCES 01-2004 in China ） have realistic and important meanings in improvement durability of concrete structures in our country.In order to guarantee better implementation off＇Guide to Durability Design and Construction of Concrete Structures＂ for designing, differences between envi- ronmental classification II in＂Code for Design of Concrete Structures＂ and corresponding class in＂Guide to Durability Design and Construction of Concrete Structures＂ are compared and analyzed.
