摘要
从波纹管、钢绞线及预应力筋控制力计算等方面,论述了预应力混凝土箱梁后张法预应力张拉前的准备工作,对后张法预应力施工张拉工艺进行了介绍,并对施工过程中遇到的问题进行了分析,积累了预应力混凝土箱梁施工经验。
The preparation work of before and after post tensioned prestressed construction control points of pre.stressed concrete box beam were discussed from accordion pipe, steel strand and prestressed control force calculation. The stretch technology of prestressed construction was introduced and the problems met in the construction progress were analyzed, which accumulated prestressed concrete box beam construction experiences.
