摘要

At the stage, the airport prestressed concrete pavement of our country is still in the research stage. In this paper, an experimental analysis on mechanical effects about the void prestressed concrete pavement has been done. Deflection has been compared under plain concrete pavement and prestressed concrete pavement by experimental methods. Experimental road panel surface size selected 2m × 1m × 0.25m. Firstly, analyze the deflection effect of ordinary concrete pavement under the void action. Secondly, analyze the deflection effect of prestressed concrete pavement under the void action. Finally, compared the deflection under the two states with plain concrete pavement and prestressed concrete pavement two pavement forms in good condition and void road, the experimental results indicates that performance of pavement is with preferential treatment to the carrier: whole prestressed concrete pavement, the viod pavement of prestressed concrete, whole plain concrete pavement, the viod pavement of plain concrete. Through the analysis, the deflection of prestressed concrete pavement is smaller about 40% than plain concrete road surface. The existence of the prestressed reinforcement makes the strength and stability greatly improved, and effectively improve the way of the bearing capacity and durability. At present, the normal operating state of the airport concrete pavement is seriously affected by the increase of its working time and the decline of the bearing capacity of the road panel under the unfavorable factors such as the emptying of the bottom of the plate. It is found that the use of prestressed concrete pavement can effectively improve the stiffness, integrity and stability of the road surface, and can effectively adapt to the emptying state of the road panel.
