    摘要：透水混凝土性能的评价表征对其工程应用有着重要意义。虽然有一些性能试验方法或标准，但是多数源于普通混凝土。而透水混凝土与普通混凝土相比，具有高孔隙率的特点，两者性能差异较大，致使许多普通混凝土的性能试验方法不适用于透水混凝土。对透水混凝土的工作性、强度、孔隙率、透水系数以及抗冻性的试验方法进行了综述，指出了目前试验方法中存在的问题，并对影响透水混凝土性能的一些因素进行了探讨。

    Abstract：The evaluation and characterization of pervious concrete performance is of great significance to its engineering application. Although there are some performance test methods or standards，most of them are derived from conventional concrete. Compared with conventional concrete，pervious concrete has the characteristics of high porosity，and the performance difference between them is relatively large，resulting in the fact that many conventional concrete performance test methods are no longer suitable for pervious concrete. The test methods of workability，strength，porosity，permeability and frost resistance of pervious concrete were reviewed，the existing problems in test methods were pointed out，and some factors influencing the performance of pervious concrete were also discussed.
