摘要
后张法预应力混凝土多用于城市立交桥和高速公路、普通公路的上跨桥,其特点是外形美观、整体性好,但施工难度比简支板大,工期长。本文主要阐述了后张法预应力混凝土箱梁的施工方法。
The concrete prestressed in post -tensioning method is largely used for urbon separation bridge and over- bridges on freeway and highway. Its characteristic is to have a beautiful contour and good integrity. But its construction difficulty is begger than one of simply - supported slab is, and time limit for a project is long. The paper mainly expounds construction procedures for concrete box beam prestressed in post -tensioning method.
