Abstract

Due to the convenience of visualization in mesoscale, numerical study on permeability and mechanical property of pervious concrete has more advantages than physical experiments in mechanism analysis of performance change. Therefore, the permeability and mechanical property of pervious concrete were studied based on numerical method on the mesostructure level. Initially, the finite element models of pore and pervious concrete were generated according to image reconstruction. Then, the permeability and mechanical property were simulated according to CFD (computation fluid dynamics) analysis and CDP (concrete plastic damage) model. Finally, the permeability was well predicted and the mechanical failure mechanism was revealed intuitively. The results indicate that numerical method is significant for deep understanding the property of pervious concrete on mesostructure level.
