摘要
在预应力混凝土双向网格井字梁结构的施工过程中,对井字梁的预应力摩擦损失、锚具变形、钢筋回缩、张拉各阶段的伸长值以及对应的跨中反拱和挠度分析,以检验梁中建立的有效预应力能否达到设计要求,并与理论分析进行比较,为确保预期的施工质量满足设计要求。
This paper tests reinforced friction loss, visetod deformation, steel reduction, elastic shrinkage and reversal deflection of curb beam in build reinforced curb structure. To examine whether effectual reinforced can satisfy design demand, results by experiment are compared with those calculated by theory. This aims to guarantee the engineering quality by testing and analyzing of prestressed concrete curb beam structure.
