| Abstract: | In comprehensive consideration of economic, environmental protection, feasiblity and other factors, jacking tech- nique is used for bridge integral jacking to solve the insufficient of clear space under bridge. This paper introduces the design points and construction process. Combined with the standard, it＇s feasiblity is analyzed theoretically and the effect of bridge integrally jacking up is verified by practice, which could provide reference for similar engineerings. |
