摘要
在预应力双向网格井字梁屋盖施工中，对井字梁的预应力摩擦损失、锚具变形、钢筋内缩、弹性压缩和反拱及挠度进行了实测，以检验梁中建立的有效预应力能否达到设计要求，并与理论值进行比较。
This paper tests reinforced friction loss, visetod deformation, steel reduction, elastic shrinkage and reversal deflection of curb beam in build reinforced curb roofing. To examine whether effectual reinforced can satisfy design demand, results by experiment are compared with those calculated by theory.
