摘　　要：通过正交试验,对影响GRC平板抗冻性能的诸多因素及水平进行优选,找出影响抗冻性能的主要因素及其影响规律;并通过对冻融结果的量化分析,给出各影响因素的主次顺序,计算出抗冻性能与诸因素水平之间的关系。根据试验结果和理论计算结果,从中优选出抗冻性能较好的材料配比组合。Some factors influencing frost resistance of GRC plate and the corresponding levels are studied, and some key factors and influencing laws are found by orthogonal experiment. The influence sequence of these key factors and their relationships with frost resistance are presented by quantitative analysis for freeze-thaw test results. According to experimental and theoretical results, several matched groups that can bring good frost resistance are obtained.
