The influences of water cement ratio，carbon fiber volume ratio and porosity on compressive strength and flexural strength of pervious concrete were analyzed through strength test of carbon fiber permeable concrete.The results show that：the compressive strength of concrete decreases with the increase of water-cement ratio，and the flexural strength increases first and then decreases with the increase of water-cement ratio，and the relative optimal water-cement ratio is 0.25-0.30.The compressive and flexural strengths first increase and then decrease with the increase of the carbon fiber volume fraction，and reach a peak when the carbon fiber volume fraction is 1.5%.The compressive and flexural strengths decrease with the increase of porosity.It is recommended to select the porosity of 10%-15% to prepare the permeable concrete.
