摘要：
The pore characteristic parameters and permeability coefficient of ceramic pervious pavement brick were obtained by using X‑ray computed tomography and three‑dimensional image reconstruction technology. Based on the influencing factors of frictional head loss and local head loss，suitable pore characteristic parameters were selected，and the quantitative relationship between permeability coefficient and pore characteristic parameters was modeled by using the dimensional analysis. The results show that the established quantitative relationship model is reasonable and reliable as proven by the statistical test method. The permeability coefficient is most influenced by effective pore tortuosity and the mean effective pore radius，and less influenced by the effective pore specific surface，the effective pore equivalent throat radius and the effective pore equivalent throat length. © 2024 Tongji University.
