| Abstract: | Taking the Youyang Gongtan bridge as a background,the article uses the bridge structure finite element calculation model to simulate and analysis the structure safety of stone arch bridge under water logging.Combined with bridge reinforcement theory,the arti-cle proposes some method such as strengthen concrete and rebar implanting for the arching,arch springing and abutment to increase its loading ability. |
