Abstract
In the context of the promotion of ecological civilization construction and the popularization of the concept of"sponge city",permeable concrete has been widely used in the construction of urban roads due to its unique functionality.The core advantage was of high porosity,which enables rapid infiltration of rainwater to mitigate surface runoff.Therefore,in order to explore the pore structure and seepage characteristics of permeable concrete,it was particularly important to carry out systematic research with the help of 3D modeling technology.A three-dimensional permeable concrete model with porosities of 9.57%and 19.48%,satisfying the real pore size distribution frequency,was constructed by randomly generating small spheres in space.The permeable concrete gel material was then generated using the mathematical morphological dilation operation.Based on the established model,the permeability was calculated by combining with Avizo software.The results showed that the porosity and connectivity of permeable concrete were the key factors affecting its permeability.When the total porosity was constant,the larger pores could increase the chance of pore size.Models with low porosity exhibit uneven pressure dropped and uneven flowed velocity distribution due to limited connectivity paths.关键词
