| Abstract: | The use of large post-tensioning pre-stressed high-performance concrete box girders used in deepwater berths especially for ore terminals to accommodate ships of more than 250 000 tons is still unprecedented in China.The paper describes that the prestressed girders are suitable for the load and process requirements through various quality control procedures during the construction of Caofeidian Ore Terminal and the successful engineering practice can provide references for similar projects. |
