| Abstract: | The demolition of continuous beam bridges is restricted by many factors,such as the design purpose,the present conditions of the structure,working conditions and so on.Taking the demolition of the old Xingxian Bridge in Suzhou as example,this paper introduced the single cantilever demolition technology and calculation analysis of a prestressed concrete beam bridge which was constructed by the symmetrical cantilever assembling method,and the result was contrasted with that of construction monitoring.This study is expected to provide successful references for the construction of other similar projects. |
