Abstract:Combined with the basic requirements of permeable brick pavement specification for permeable design, through the analysis of rainstorm intensity, permeable coefficient of permeable brick and permeability performance of soil foundation, taking a parking lot in Tangshan city of Hebei Province as an example, this paper explores a new idea for permeable design of sections with insufficient permeable capacity of soil foundation, puts forward the method of setting permeable channel and carries out layout design, The application scope of permeable pavement structure is expanded.
