高性能混凝土在公路简支板桥中的应用研究

Study on the application of the high performance concrete in the simple supported slab bridge of the highway

用C80高性能混凝土对公路简支板桥进行了优化设计研究,阐述了C80HPC板与普通混凝土板相比,在板体自重、梁高、预应力筋用量等方面的变化情况,并分析了其经济效益。

The author carries out the optimal design of the simple supported slab bridge in the highway by using the C80 high performance concrete, describes the change situation of the dead weight of the slab, the beam height and the amount of the prestressed reinforcement compared with the common concrete slab, and analyzes its economic benefit.
