桥梁高效混凝土配合比优化设计及其性能研究

Optimization of concrete mix design and the performance of bridges with high-performance concrete

箱梁是超长、大跨径连续刚构桥梁的关键承重构件,由于长年在复杂的环境中使用,对其所用混凝土进行综合研究是十分必要的。根据箱梁混凝土的设计要求,通过混凝土配合比优化设计及性能试验研究,探索获得优质高效混凝土新途径;为施工提供参数和指导。

Box girder is a key component of the long-span continuous rigid-framed bridge.It is very necessary to study on the high-performance concrete because of the complicated circumstances.According to the design requirements, the new approach to obtaining high-performance concrete for the construction is explored through studying on the optimization of concrete mix design and the performance.
