Steel Carbon Fiber Combination Reinforced Curved Arch Bridge Technology Research,

There are lots of ways by which the double arch bridge can be successfully reinforced. Therefore, one measure that is based on the tapered arch section mechanics mechanism has never been used.After reinforced, the arch section become the tapered arch section which makes the mechanics mechanism changed. This research brings forward a new measure which is based on the change. Based on the practical engineering, the article draws the following conclusion:1. The moment of the arch section lies on the change of the moment of inertia. To the moment of inertia get bigger from arch tope to the no gemel arch footsie, the moment get bigger from arch tope to the arch footsie. Utilizing thischaracteristic, the author puts forward the reinforced measure—steelplate-carbon fibre reinforce the double arch bridge which can "transfer" the load from the arch top to the arch footsie which can directly lighten the burden of the arch top.2. The measure of steel plate-carbon fibre reinforce the double arch bridge not only utilizes the arch section's mechanics mechanism, but also exerts the strongpoint of two reinforce measures.In the same time, the research discusses the following problems:1. Bring forward the new arch model which uses the plate element to simulate the self-weight and the combining function and discuss the connecting problem between the beam element and the plate element. Drawing conclusion that the model no end releasing can also well simulate the practice.2. Discussing the method of the section conversion and drawing the conclusion that the method which is base on the Modulus of Elasticity.3. Bring forward the new calculate method that point out that in the course of calculating the dead load , the solid abdomen segment should be devided into two different segment.
