Study on the Anti-Cracking of GFRP Bars Asphalt Concrete Bridge Deck Pavement under the Vehicle Load

Abstract:

the mechanical analysis of bridge deck pavement is limited at home and abroad.As is known to all,when we referred to the load-carrying capability of a bridge, the deck pavement is surely the weakest part. It is necessary to analyze the distribution of stress on bridge deck pavement, then design the pavement reasonably. In this paper, the model of bridge deck structure can be analyzed using solid model of bridge deck established in the principle of the finite element software. The analysis mainly includes two sides: one is analyzing the tensile stress of the deck caused by vehicle from Horizontals and verticals;the other is about finding the position of the most unfavorable load, and replacing corrosion-resistant GFRP with common steel ,then establishing GFRP reinforced asphalt bridge deck solid model. The author will analyze the setting states and the most suitable location of GFRP bras under the vehicle load on the bridge deck. At last we make the conclusion that the GFRP bars can effectively undertake the stress to prevent cracking.
