Analysis of Bridge Replacement Scheme Without Interrupting Traffic
In order to improve the flood discharge capacity of existing rivers,dredging some existing rivers.Due to the limitation of early planning and design,the original bridge structure which intersects with the dredged river can not meet the need of force after the dredged river.The project investment will be relatively high by means of in-situ reconstruction of interrupted highway traffic or reloca-tion of highway lines.Taking the pier replacement of Jiuxianghe Bridge 14#～19#in the first phase of Qinhuai East River Project in Nanjing as the background,the influence of dredging and digging on existing expressway bridges is fully considered,and the rationality of the bridge pile replacement scheme is demonstrated from the stress of bridge superstructure,bearing capacity of pile foundation and seismic resistance.The bridge pile foundation replacement scheme suitable was finally determined.
