摘　　要：分析了现阶段我国特大型桥梁混凝土生产过程中存在着原材料重视不足、生产质量控制不严和取样代表性不强等问题以及其产生的主要根源,从生产管理的角度提出了设立单独拌和站集中拌和的生产模式解决方案。该方案具有提高混凝土生产控制水平、混凝土匀质性,提高拌和楼使用率和降低资金投入等优点,可有效地提高桥梁混凝土的生产质量。The existing problems during the production of concrete used for extra large bridge in China are analyzed such as insufficient attention to raw materials, lack of strict quality control measures and untypical sampling, as well as the causes of such problems. A solution scheme that set up of separate mixing station for central mixing is proposed from the perspectives of production management. This scheme can enhance the production and control level of concrete, its uniformity, increase the usage frequency of mixing platform and reduce capital investment, etc, which can effectively improve the quality of concrete used for bridge.
