摘要
针对移动模架施工荷载工况变化较多的特点,结合九江大桥南引桥工程实际,对50 m预应力混凝土箱梁采用移动模架施工过程进行应力测试,并与理论计算对比分析,效果较好,为指导施工和保证工程施工质量有重要意义。
According to the characteristics of moved model load changeable conditions,combined with the actuality of the south approach of Jiujiang Bridge,a stress test is presenfed on 50 m PC Box Beam by applying moved model construction method,and then relatively analyzed the test results and the theoretical calculation.It shows that the test results are satisfactory.The results play important role in directing the construction and ensuring the construction quality.
