摘要
在广州市某公路桥梁施工中 ,为减少预应力损失及了解钢绞线的应力状况 ,对多转角长束预应力钢绞线张拉进行测试 ,为改进施工工艺和结构补强设计提供了依据。
To decrease prestressed loss and realize stress distribution of the strand,stress of multi\|corner long prestressed strand was tested by stretching.Based on these test data construction proceedings were improved and structural reinforcement was designed.
