| 中文摘要: |
| 介绍了苏通大桥在设计、施工、科研方面采取的优化钢筋保护层厚度、优选原材料、优化配合比、开展混凝土施工质量全程控制等耐久性保障措施,与设计值相比,控制后施工配合比水胶比方差≤5,保护层厚度合格率达到85%以上. |
| 英文摘要: |
| The article introduces measures on design, construction and research for concrete structure durability of Sutong bridge, including optimizing concrete thickness cover to reinforcement , optimizing raw material selection , optimizing concrete mix proportion and carrying out whole process control on construction quality which all are applied successfully. Compared with design value,variance of water to binder ratio is smaller than 5 or equal to 5, concrete cover qualified rate is more than 85% . |
