摘要
预应力混凝土结构长期在使用环境作用下,其性能随时间而逐渐减退,最终破坏,其实质就是预应力混凝土结构的耐久性问题。本文根据预应力混凝土结构的构成,分别从钢筋和混凝土两方面阐述了混凝土结构的耐久性问题,从而为工程设计、施工和施工管理提供了可靠的依据。
Under using environment, the performance of prestressed concrete structure is gradually decreased with its using time, and finally destroyed. In fact, the reason is durability of prestressed concrete structure. In this paper, according to the structure of prestressed concrete, the durability of prestressed concrete structure is set forth from the reinforcing steel bar and the concrete, and so the dependable foundation is provided for design and construction and construction management.
