| 摘 要： | 正交试验设计理论应用到高性能钢管混凝土配合比设计中,仅需少量试验即可完成对诸多配合比影响因素不同位级的考察研究。以高安筠州大桥钢管混凝土配合比设计为例开展试验研究工作,利用正交试验方法分析研究了各外掺剂对钢管混凝土的流动性和强度性能的影响规律及其影响的显著性,得到了符合设计和施工要求的配合比设计方案。将数理统计原理应用于高性能钢管混凝土试验研究中,对材料研究及工程实践都有着重要的指导意义,研究成果可为类似工程提供参考。

| Abstract: | Adopting orthogonal design method in the CFST mix design,only a few experiments would be needed in the study on many influential factors with different level in mix design.The authors studied the CFST mix design of GaoAn YunZhou Bridge as an example,analyzed the influential patterns of CFST workability and strength with different additives.The significance of influential factors were(determined) by the experiment,and better mix design which meet the design and construction requirements was obtained.The approach to applying mathematic statistics in the mix design of high performance CFST plays significant role in the material study and engineering practice.The results of experiment study can be refereuce to other similar projects. |
