正交试验法在高速公路基层配合比设计中的应用探讨

Discussion on Orthogonal Experimentation Applied in Basic Mixture Proportion Design of Expressway

在高速公路基层配合比设计中,影响水泥稳定碎石强度的除了水泥剂量外,还有其他多种因素,这就要求我们在配合比设计时尽可能充分地考虑这些因素,挑选出既经济合理、满足规范技术要求又施工方便的配合比。正交试验法无疑是一种切合实际、省工省时的试验方法。

During the basic mixture proportion design of expressway,there are many factors affect the intension of stable concrete gravels besides the concrete dosage,which should be considered enough,and the economical one that satisfies the technique criterion and convenient for construction should be chosen. Without fail,orthogonal experimentation is just the one method fitting for practice with time-saving and work-saving.
