摘要：钢管混凝土配合比设计，目前一直没有一种大家公认的设计方法。文中提出把正交试验设计应用于高性能微膨胀钢管混凝土配合比设计中，并以高安筠州大桥工程实例，详细介绍了制订试验计划及进行试验结果分析的方法，可供同行参考。

The Application Research of Orthogonal Experiment in CFST Mix Design

ZHANG Hong¹ ,FANG Hua¹,HUANG Peng²,YE Feng²

Abstract: There is no method accepted universally in mix design of CFST at present. The orthogonal experiment design method is proposed for high-performance and mini-expansion CFST mix designs. The plan and the results analysis` method of the experiment are introduced detailed combination with the construction of Gao`an YunZhou bridge, and give a reference for similar project.
