摘　　要：文章首先通过变Ⅰ法对透水混凝土的级配进行研究,给出了相对合理的级配范围;然后通过对透水混凝土的性能进行研究,得出了强度与水泥用量、有效孔隙率和水泥用量的关系以及强度随时间的增长规律,对透水混凝土的设计具有重要意义。Through the study on the gradation of permeable concrete based on method of I Change,the paper gives a relatively reasonable scope of gradation;then through the study on the performance of the permeable concrete,the relationships between the strength and cement dose,the effective porosity and cement dose were found and the regulation of the strength with the time was got,which are helpful to the design of the permeable concrete.
