| Abstract: | The crack-control technology of the super-long basement structure of Shanghai BAILIAN International Square is introduced in this paper. The length and width of the basement are 215.7m and 172.2m. Based on the results of FEM calculation, comprehensive crack control methods are adopted in the design of the basement, which include prestressing technology, two-layer welded steel fabric technology, and microdilatancy waterproofing agent utility technology of concrete. The technology is proved to be effective and successful, and is of great help to the design of other super-long structures. |
