Abstract:
Permeable pavement system has been widely used in the construction of sponge cities due to its well characteristics of promoting seepage and emission reduction for rainwater runoff. However, mature calculation and monitoring methods of permeation performance have not been established during the study and application of permeable pavement domestic and international. Through a review of the calculation methods of permeability coefficients, the calculation methods of permeability coefficients of permeable pavements are systematically analyzed. The limitations of monitoring methods based on Darcy’s law in practical engineering applications were explored. According to the applicable conditions of the derived formulas based on Darcy’s law, the feasibility of the derived formula for calculating the infiltration process of permeable pavement was put forward, which provide a scientific basis for the popularization and application of permeable pavement and effect evaluation.
