摘　　要：　荆州长江公路大桥是江汉平原上的重要跨江通道,设计为斜拉索混凝土桥。其跨度大,泵送距离远,部分部位为大体积混凝土施工。本文根据设计和施工要求的混凝土的耐久性、工作性能和抗压强度等力学性能,合理选择施工使用的原材料,在检测分析各原材料物理和化学特性基础上,通过正交试验对荆州长江公路大桥主梁C60混凝土施工配合比进行优化设计研究。The Yangtze River highway bridge of Jingzhou is an important passageway crossing the River in the Jianghan plain,which is designed as cable-stayed concrete bridge.The distance bumping concrete is long because its span is large,and the parts of its is large volume concrete,so the materials of concrete must be chosen rationally on the base of durability,working performance and mechanical property such as compressive strength that meet the requirements of the design and construction.In this paper,the optimum research of mix proportion of the bridge's C60 concrete through orthogonal test on the base of the physical and chemical property of these materials are detected and analyzed.
