We analyze existing masonry arch-bridges and corresponding reinforcement methods in this paper and bring about the method of using strip-shaped outer-wrap reinforced concrete with chemically planted bar to improve the new and old concretes cooperative work so as to strengthen the wholeness and improve impermeability of the bridge. We also compare two experiments on one actual bridge of 30 cm strip-shaped outer-wrap reinforced concrete in the main arch ring and 20 cm global outer-wrap reinforcement concrete, of which the data shows the superiority of strip-shaped outer-wrap reinforced concrete for it strengthens both the bridge floor and bottom structure and improve the load capacity.

Reinforced concrete masonry arch aqueduct is a common water diversion engineering structure. Aqueduct is decorated on the concrete cushion layer, cushion layer effects on masonry arch, the structures stress is uniform, carrying capacity is strong. This paper adopts finite element method to carry out force analysis for reinforced concrete masonry arch aqueduct of Lijia pumping station, considering aqueduct weight, water pressure and earthquake effect, etc. Researching stress and deformation distribution law of reinforced concrete masonry arch aqueduct.
