| Abstract: | The 34 40.6-m simple-supported box girders of the Yangtze River Bridge at Tianxingzhou are cast in place with two sets of self-propelled forming frames made in Norway. The paper introduces the structural formation and working principles of the forming frame, with stress placed on the key techniques such as the fixing of the forming frame, the pre-pressurizing of the forming frame, the fixing of the supports, as well as the construction of the box girders. |
