| Abstract: | By combining with some examples,the paper,according to the research on the factual characteristics of bridges,its diseases and their reasons,illustrates the adoption of three-layer concrete wrapping,the pouring concrete on the superior margin of arch s back of the main arch ring,the addition of umbrella arch in inferior margin of the side arch ring on the main arch beam,which are based on the theoretical analysis of the structure,so as to improve the loading capacity of the bridge. |
