浅谈后张法预应力混凝土施工工艺

Study on the construction technique of the post-tensioning prestressed concrete

从20世纪60年代起,预应力混凝土结构经过几十年的工程实践和研究,已发展成为一项比较成熟的工程技术,其原理广泛应用于房屋建筑、桥梁工程等结构领域。文章简要介绍了预应力混凝土的概念,后张法预应力混凝土的主要施工工艺。

Since 1960s,prestressed concrete is widely used in building construction. After decades of the engineering practice and constant study,prestressed technology has become a mature engineering technology relatively,whose principle is widely used in housing construction, bridge and other structural areas. This article briefly describes the concept of the prestressed concrete and the main construction technique of the post-tensioning prestressed concrete.
