桥梁施工后张法预制箱梁的张拉控制桥梁施工后张法预制箱梁的张拉控制 摘要:后张法有粘结预应力技术一般用于预制大跨径简支梁、简支板结构,屋面梁、屋架结构,各种现浇预应力结构或块体拼装结构
该技术在房屋建筑、特种结构、桥梁结构中都有广泛的应用
在桥梁施工中,预应力混凝土后张法也有很大的应用,特别是后张法在预制箱梁的应用,对于这种施工工艺对预应力混凝土的张拉有很大的要求
本文主要阐述了在桥梁施工中后张法预制箱梁的张拉控制

This technology in housing construction, special structure, the bridge structure are widely used
In bridge construction, prestressed concrete method after a have a great application, especially after a method in the application of the precast concrete box girders, for this kind of construction technology of p
