摘要
结合我国某高铁预应力混凝土简支箱梁采用后张法施工的过程,简要论述三项关键工序、高性能混凝土耐久性指标的保证措施、减小箱梁后期徐变的相关施工措施及注意要点,以确保满足高速铁路运营的安全性、高速度、高平顺性和舒适度.
The critical activity to ensure the durability of the high performance concrete index and reduce the late box girder creep was introduced according to post-tensioning method applied in one high-speed rail concrete box beam construction procedures. The critical activity can meet the requirements of security, high-speed, quiet running property, comfort.
