一、概述预应力混凝土桥梁的施工方法对桥梁的设计、施工和造价影响甚大,故在选定施工方法时,务必充分掌握各种施工方法的适用性。预应力混凝土梁的施工方法,一般可大致分为现浇混凝土施工法和预制混凝土施工法。现浇混凝土施工法包括:在地面搭设的支架上现浇施工(固定式支架),将混凝土梁

I. Overview The construction methods of prestressed concrete bridges have a great impact on the design, construction and cost of bridges. Therefore, it is imperative to fully understand the applicability of various construction methods when selecting construction methods. Prestressed concrete beam construction methods can generally be divided into the construction method of cast-in-place concrete and precast concrete construction method. Cast-in-place concrete construction methods include: cast-in-place construction of the stent on the ground (fixed bracket), the concrete beam
