摘　　要：强度和透水性之间的矛盾是影响透水混凝土大面积推广应用的主要因素之一,易遭受冻融破坏又是其在北方寒区水利工程中广泛应用的重要障碍。采用正交试验的方法,对寒区冻融条件下的透水混凝土配合比展开优化试验研究。根据试验结果,提出北方寒区透水混凝土配制的最佳配合比。The contradiction between strength and water permeability is one of the main factors that affect the wide application of pervious concrete,and its vulnerability to freeze-thaw damage is an important obstacle to its wide application in water conservancy projects in the cold region of North China.In this paper,the orthogonal test method is used to optimize the mix proportion of pervious concrete under freezing and thawing conditions in cold region.According to the test results,the best mix proportion of pervious concrete in north cold area is put forward.

关 键 词：冻融破坏 透水混凝土 动弹模量
