摘　　要：通过对竖向预应力粗钢筋的锚固工艺试验及预应力损失的检测 ,得到了保证有效预应力的可行方法 ,分析了竖向预应力钢筋应力损失的规律 。By the study of the auchorage technique experiment and the prestress loss test of vertical prestressed reinforcement, a practicable method for ensuring the offective vertical prestress of long span continuous rigid framed bridge is obtained, and the variational laws of vertical prestress loss are analyzed in the paper. It may be used for reference for prestress reinforcement construction of similar bridges.
