Abstract
At present,the step of simply supported beam at first and the continuous box beam and support cast-in-place continuous beam after it is used in the design and construction of bridge with the small and medium span,but all these two forms have the certain insufficiency.The assembly continuous beam bridge is a new form of structure combining the precast beam with the cast-in-place beam,which synthesizes the merits of the other two forms and makes up their insufficiency. So it is a new idea and method in the design and construction of the beam bridge with the medium span.
