混凝土结构耐久性环境区划标准的目的就是为混凝土结构耐久性设计提供合理的设计参数.混凝土结构耐久性环境区划标准在结构全寿命周期成本原理基础上考虑了环境对结构的影响,并将结构的重要性、结构形式和功能等多方面因素一并纳入考虑之中.首先给出了混凝土结构设计耐久性环境区划标准的概念和建立该标准的3个基本原则,其次根据自然环境条件和结构重要性等确定了区划的主要影响因素,然后以浙江省公路桥梁结构耐久性环境区划图的编制为例说明了混凝土结构耐久性环境区划的可行性与实用性,最后根据区划图给出了耐久性区划标准的若干设计规定.
The purpose of the standard for environmental durability of concrete structures is to provide reasonable design parameters for durability design of concrete structures.Environmental standards for durability of concrete structures take into account the impact of environment on the structure based on the life cycle cost principle of the structure, Importance, structure and function of the concrete structure.Considering the conception of the standard of environmental durability of concrete structure design and three basic principles of establishing the standard, and secondly, according to the importance of natural environment and structure The main influencing factors of zoning are determined. Then, the feasibility and practicability of the durable environmental zonation of concrete structures are illustrated with the compilation of the zoning map of the durability of the highway bridges and bridges in Zhejiang Province. Finally, the durability Several design requirements for zoning standards.
