摘要：海绵城市建设中使用的面层铺装透水材料种类繁多，透水材料透水系数的测试方法也不尽相同：按不同标准试验方法，采用固定水位法和固定水量法对透水混凝土透水系数进行测试；改变水位差和试样厚度，采用固定水位法对透水混凝土和透水路面板透水系数进行测试；改变水位差和试样厚度，采用固定水量法对透水混凝土透水系数进行测试。对透水系数相关试验过程和测试结果进行统计分析，总结试验方法存在的问题和影响测试结果的因素。

Abstract：There are many kinds of surface pavement permeable materials used in sponge city construction，and the test methods of permeability coefficient of permeable materials are different. According to different standard test methods，the permeability coefficient of pervious concrete is tested by fixed water level method and fixed water volume method. The permeability coefficients of permeable concrete and permeable pavement slabs are tested by changing the water level difference and the thickness of the sample. The permeability coefficient of pervious concrete is tested by fixed water volume method by changing water level difference and sample thickness. Through statistical analysis of permeability coefficient related test process and test results，the existing problems of test methods and factors affecting test results are summarized.
