ABSTRACT

Channels are very common structures in highway engineering. Most of the traditional channels are cast-in-situ, however, the construction quality cannot be guaranteed and the durability is not as well as expected. In recent years, the fabricated channel has been used more often, but which form is the best for fabricated construction still needs to be figured out. This paper studies the structure performance of a double-hinged four-component fabricated reinforced concrete box channel via numerical analysis and field experiments. The results show the fabricated channel has good mechanical performances. The channel releases the side wall bending moment by providing structural hinges on the side wall and optimizes the internal force status of channel parts. On the other hand, components of the fabricated structure weigh less and are easier to transport to the destination, which satisfies the requirements of fabricated construction. The fabricated channel has great value in the related area.
