目前预应力技术已经广泛地应用于工程的各个领域,在大跨度桥梁结构与大跨度、高层房屋中的应用更是蒸蒸日上。预应力技术已经进入了高速的发展阶段,目前已遍及建筑、桥梁、电视塔、核电站安全壳、混凝土采油平台、水处理和水池等。预应力混凝土是显著改善构件抗裂性能的有效途径。本篇文章主要介绍预应力结构的发展历史,预应力混凝土的特点,预应力混凝土的分类和预应力结构应用的发展。
At present, prestressing technology has been widely used in various fields of engineering, and the application in the long-span bridge structure, long-span and high-rise buildings is booming. Prestressed technology has entered a high-speed development stage, now has over buildings, bridges, TV towers, nuclear power plant containment, concrete production platform, water treatment and pool. Prestressed concrete is an effective way to significantly improve crack resistance. This article mainly introduces the development history of prestressed structure, the characteristics of prestressed concrete, the classification of prestressed concrete and the development of prestressed structure.
