| 摘 要： | 应用逾渗理论，损伤力学等相关理论分析水泥混凝抗土抗冻性中的强度下降问题，对这些逾渗现象进行了分析，提出了唯象学的新观点，合理地解释了当前关于高强混凝土抗冻性研究结果不一致的问题，并进而提出了改进措施。

| Abstract: | In this paper, theories, such as percolation theory, damage theory, etc, are adopted to analyze the strength reduction during the freezing and thawing process in cement_based composite. The percolation phenomenom is analyzed and the new theory based on the phenomenology is proposed which can reasonably interpret the non_homogeneity in the research results of the frost resistance of high strength concrete. Further on, improving measures for forst resistance are put forward. |
