| Abstract: | This paper,taking the successful rebuilding case of a certain old dock in Zhenjiang Port as an example,summarizes the common technical difficulties in dealing with the bounding of the new structures with old ones of docks through design and construction practices of four typical boundings such as the pile cap,track beam's joint,sewage tank and track beam's support.It also expounds the corresponding treatment measures and application of some new technologies. |
