摘要
结合后张法预应力的施工体会,详细分析了对束筋伸长量影响较大的物理参数,提出了相应的修正方法,并通过具体算例予以验证,为后张法预应力混凝土结构的设计和施工提供了有意义的指导。
The paper analyses the main physical parameter to the stretching elongation with the prestressing construction experience, and gaves the corresponding revision methods, confirms that they are accurate by an example, provides maningful guidance for the design and construc- tion of post-tensioned pretressed concrete structure.
