The invention discloses a permeable pavement structure with high strength and high permeability. The permeable pavement structure comprises a water isolating seal layer, a base layer and a surface layer which are sequentially arranged on a soil matrix; the surface layer comprises a permeable framework, and concrete positioned among pores of the permeable framework; the permeable framework comprises transverse vent pipes which are communicated with one another and vertical osmosis pipes vertically arranged on the transverse vent pipes; the base layer comprises rubble layer at the upper layer and a sand mat at the lower layer; and the water isolating seal layer comprises a water isolating membrane. The high-density concrete in the surface layer has the advantages of high strength and high durability, and the permeable framework in the concrete can guide rainfall into the base layer so as to prevent accumulation of rainfall on the pavement. Rubbles in the rubble layer are overlapped so as to form a flowing passage for rainfall, thus playing the role in delivering water and improving the strength of the base layer. Macadams in the sand mat can decelerate infiltration of the rainfall, thus playing the roles in storing water, discharging water and improving the strength of the base layer; and the water isolating membrane can prevent the rainfall from permeating into the soil matrix.
